(#97871)
…lly registered languages
First of all, this is done to support exceptions for the Mojo language,
but it's done in a way that will benefit any other plugin language.
1. I added a new lldb-dap CLI argument (not DAP field) called
`pre-init-commands`. These commands are executed before DAP
initialization. The other `init-commands` are executed after DAP
initialization. It's worth mentioning that the debug adapter returns to
VSCode the list of supported exception breakpoints during DAP
initialization, which means that I need to register the Mojo plugin
before that initialization step, hence the need for `pre-init-commands`.
In general, language plugins should be registered in that step, as they
affect the capabilities of the debugger.
2. I added a set of APIs for lldb-dap to query information of each
language related to exception breakpoints. E.g. whether a language
supports throw or catch breakpoints, how the throw keyword is called in
each particular language, etc.
3. I'm realizing that the Swift support for exception breakpoints in
lldb-dap should have been implemented in this way, instead of hardcoding
it.

Remove the last remaining references to the reproducers from the
instrumentation. This patch renames the relevant files and macros.

This patch removes most of the reproducer instrumentation. It keeps
around the LLDB_RECORD_* macros for logging. See [1] for more details.

A long time ago LLDB wanted to start using StringRef instead of
C-Strings/ConstString but was blocked by the fact that the StringRef constructor
that takes a C-string was asserting that the C-string isn't a nullptr. To
workaround this, D24697 introduced a special function called `withNullAsEmpty`
and that's what LLDB (and only LLDB) started to use to build StringRefs from
C-strings.
A bit later it seems that `withNullAsEmpty` was declared too awkward to use and
instead the assert in the StringRef constructor got removed (see D24904). The
rest of LLDB was then converted to StringRef by just calling the now perfectly
usable implicit constructor.
However, all the calls to `withNullAsEmpty` just remained and are now just
strange artefacts in the code base that just look out of place. It's also
curiously a LLDB-exclusive function and no other project ever called it since
it's introduction half a decade ago.
This patch removes all uses of `withNullAsEmpty`. The follow up will be to
remove the function from StringRef.

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).

Move SBRegistry method registrations from SBReproducer.cpp into files
declaring the individual APIs, in order to reduce the memory consumption
during build and improve maintainability. The current humongous
SBRegistry constructor exhausts all memory on a NetBSD system with 4G
RAM + 4G swap, therefore making it impossible to build LLDB.

This patch adds the SBReproducer macros needed to capture and reply the
corresponding calls. This patch was generated by running the lldb-instr
tool on the API source files.

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.

*** to conform to clang-format’s LLVM style. This kind of mass change has
*** two obvious implications:
Firstly, merging this particular commit into a downstream fork may be a huge
effort. Alternatively, it may be worth merging all changes up to this commit,
performing the same reformatting operation locally, and then discarding the
merge for this particular commit. The commands used to accomplish this
reformatting were as follows (with current working directory as the root of
the repository):
find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} +
find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ;
The version of clang-format used was 3.9.0, and autopep8 was 1.2.4.
Secondly, “blame” style tools will generally point to this commit instead of
a meaningful prior commit. There are alternatives available that will attempt
to look through this change and find the appropriate prior commit. YMMV.

Summary:
Add language option in -gdb-show command + test:
```
$ bin/lldb-mi ~/p/hello
[...]
b main
[...]
r
[...]
(gdb)
-gdb-show language
^done,value="c++"
(gdb)
quit
```
