In preparation for removing the `#include "llvm/ADT/StringExtras.h"`
from the header to source file of `llvm/Support/Error.h`, first add in
all the missing includes that were previously included transitively
through this header.
This is fixing all files missed in b0abd4893fa1, 39d8e6e22cd1, and
a11efd49266f.

Applied modernize-use-default-member-init clang-tidy check over LLDB.
It appears in many files we had already switched to in class member init but
never updated the constructors to reflect that. This check is already present in
the lldb/.clang-tidy config.

This converts a default constructor's member initializers into C++11
default member initializers. This patch was automatically generated with
clang-tidy and the modernize-use-default-member-init check.
$ run-clang-tidy.py -header-filter='lldb' -checks='-*,modernize-use-default-member-init' -fix
This is a mass-refactoring patch and this commit will be added to
.git-blame-ignore-revs.

The C headers are deprecated so as requested in D102845, this is replacing them
all with their (not deprecated) C++ equivalent.

Somehow UBSan would only report the unaligned load in TestLinuxCore.py
when running the tests with reproducers. This patch fixes the issue by
using a memcpy in the GetDouble and the GetFloat method.

Summary:
LLVM is using its own isPrint/isSpace implementation that doesn't change depending on the current locale. LLDB should do the same
to prevent that internal logic changes depending on the set locale.

AVR usually uses two byte addresses. By making DataExtractor deal with
this, it is possible to load AVR binaries that don't have debug info
associated with them.

This function is equivalent to GetAddress, but getAddress is also
present on the llvm version of the data extractor.

Shafik suggested this cleanup in https://reviews.llvm.org/D73913.

DataExtractor::GetMaxS64Bitfield performs a shift with UB in order to
construct a bitmask when bitfield_bit_size is 64. The current
implementation actually does “work” in this case, because the assumption
that the shift result is 0 holds, and 0 minus 1 gives the all-ones value
(the correct mask). However, the more readable/maintainable approach
might be to use an off-the-shelf UB-free helper.

Summary:
A *.cpp file header in LLDB (and in LLDB) should like this:
```
//===-- TestUtilities.cpp -------------------------------------------------===//
```
However in LLDB most of our source files have arbitrary changes to this format and
these changes are spreading through LLDB as folks usually just use the existing
source files as templates for their new files (most notably the unnecessary
editor language indicator `-*- C++ -*-` is spreading and in every review
someone is pointing out that this is wrong, resulting in people pointing out that this
is done in the same way in other files).
This patch removes most of these inconsistencies including the editor language indicators,
all the different missing/additional '-' characters, files that center the file name, missing
trailing `===//` (mostly caused by clang-format breaking the line).

guarenteed to be 64 bit
GetMaxU64Bitfield(...) uses the ul suffix but we require a 64 bit unsigned integer and ul could be 32 bit. So this replacing it with a explicit cast and refactors the code around it to use an early exit.

that function.
Summary:
The `if (*cstr_end == '\0')` in the previous code checked if the previous loop terminated because it
found a null terminator or because it reached the end of the data. However, in the case that we hit
the end of the data before finding a null terminator, `cstr_end` points behind the last byte in our
data and `*cstr_end` reads the memory behind the array (which may be uninitialised)
This patch just rewrites that function use `std::find` and adds the relevant unit tests.

Replaces the remaining C-style casts with explicit casts in Utility. The
motivation is that they are (1) easier to spot and (2) don't have
multiple meanings.

A lot of comments in LLDB are surrounded by an ASCII line to delimit the
begging and end of the comment.
Its use is not really consistent across the code base, sometimes the
lines are longer, sometimes they are shorter and sometimes they are
omitted. Furthermore, it looks kind of weird with the 80 column limit,
where the comment actually extends past the line, but not by much.
Furthermore, when /// is used for Doxygen comments, it looks
particularly odd. And when // is used, it incorrectly gives the
impression that it's actually a Doxygen comment.
I assume these lines were added to improve distinguishing between
comments and code. However, given that todays editors and IDEs do a
great job at highlighting comments, I think it's worth to drop this for
the sake of consistency. The alternative is fixing all the
inconsistencies, which would create a lot more churn.

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

This patch removes the comments following the header includes. They were
added after running IWYU over the LLDB codebase. However they add little
value, are often outdates and burdensome to maintain.

Summary:
During the previous attempt to generalize the UUID class, it was
suggested that we represent invalid UUIDs as length zero (previously, we
used an all-zero UUID for that). This meant that some valid build-ids
could not be represented (it's possible however unlikely that a checksum of
some file would be zero) and complicated adding support for variable
length build-ids (should a 16-byte empty UUID compare equal to a 20-byte
empty UUID?).
This patch resolves these issues by introducing a canonical
representation for an invalid UUID. The slight complication here is that
some clients (MachO) actually use the all-zero notation to mean "no UUID
has been set". To keep this use case working (while making it very
explicit about which construction semantices are wanted), replaced the
UUID constructors and the SetBytes functions with named factory methods.
- "fromData" creates a UUID from the given data, and it treats all bytes
equally.
- "fromOptionalData" first checks the data contents - if all bytes are
zero, it treats this as an invalid/empty UUID.

This is intended as a clean up after the big clang-format commit
(r280751), which unfortunately resulted in many of the comment
paragraphs in LLDB being very hard to read.
FYI, the script I used was:
import textwrap
import commands
import os
import sys
import re
tmp = "%s.tmp"%sys.argv[1]
out = open(tmp, "w+")
with open(sys.argv[1], "r") as f:
header = ""
text = ""
comment = re.compile(r'^( *//) ([^ ].*)$')
special = re.compile(r'^((([A-Z]+[: ])|([0-9]+ )).*)|(.*;)$')
for line in f:
match = comment.match(line)
if match and not special.match(match.group(2)):
# skip intentionally short comments.
if not text and len(match.group(2)) < 40:
out.write(line)
continue
if text:
text += " " + match.group(2)
else:
header = match.group(1)
text = match.group(2)
continue
if text:
filled = textwrap.wrap(text, width=(78-len(header)),
break_long_words=False)
for l in filled:
out.write(header+" "+l+'\n')
text = ""
out.write(line)

* Prevent dumping of characters in DumpDataExtractor() with
item_byte_size bigger than 8 bytes. This case is not supported by the
code and results in a crash because the code calls
DataExtractor::GetMaxU64Bitfield() -> GetMaxU64() that asserts for
byte size > 8 bytes.
* Teach DataExtractor::GetMaxU64(), GetMaxU32(), GetMaxS64() and
GetMaxU64_unchecked() how to handle byte sizes that are not a multiple
of 2. This allows DumpDataExtractor() to dump characters and booleans
with item_byte_size in the interval of [1, 8] bytes. Values that are
not a multiple of 2 would previously result in a crash because they
were not handled by GetMaxU64().

This patch makes adjustments to header file includes in
lldbUtility based on recommendations by the iwyu tool
(include-what-you-use). The goal here is to make sure that
all files include the exact set of headers which are needed
for that file only, to eliminate cases of dead includes (e.g.
someone deleted some code but forgot to delete the header
includes that that code necessitated), and to eliminate the
case where header includes are picked up transitively.

In doing so, clean up the MD5 interface a little. Most
existing users only care about the lower 8 bytes of an MD5,
but for some users that care about the upper and lower,
there wasn't a good interface. Furthermore, consumers
of the MD5 checksum were required to handle endianness
details on their own, so it seems reasonable to abstract
this into a nicer interface that just gives you the right
value.
