Printing IR spends a large amount of time updating the column count via
generic UTF-8 APIs. Speed it up by adding a fast path for the common
printable ASCII case.
This makes `-print-on-crash -print-module-scope` about two times faster.

The color methods in formatted_raw_ostream were forwarding directly to
the underlying stream without considering existing buffered output. This
would cause incorrect colored output for buffered uses of
formatted_raw_ostream.
Fix this issue by applying the color to the formatted_raw_ostream itself
and temporarily disabling scanning of any color related output so as not
to affect the position tracking.
This fix means that workarounds that forced formatted_raw_ostream
buffering to be disabled can be removed. In the case of llvm-objdump,
this can improve disassembly performance when redirecting to a file by
more than an order of magnitude on both Windows and Linux. This
improvement restores the disassembly performance when redirecting to a
file to a level similar to before color support was added.

With C++17 there is no Clang pedantic warning or MSVC C5051.

* The getLine and getColumn functions need to update the position, or
they will return stale data for buffered streams. This fixes a bug in
the clang -analyzer-checker-option-help option, which was not wrapping
the help text correctly when stdout is not a TTY.
* If the stream contains multi-byte UTF-8 sequences, then the whole
sequence needs to be considered to be a single character. This has the
edge case that the buffer might fill up and be flushed part way
through a character.
* If the stream contains East Asian wide characters, these will be
rendered twice as wide as other characters, so we need to increase the
column count to match.
This doesn't attempt to handle everything unicode can do (combining
characters, right-to-left markers, ...), but hopefully covers most
things likely to be common in messages and source code we might want to
print.

This adds the --debug-vars option to llvm-objdump, which prints
locations (registers/memory) of source-level variables alongside the
disassembly based on DWARF info. A vertical line is printed for each
live-range, with a label at the top giving the variable name and
location, and the position and length of the line indicating the program
counter range in which it is valid.
Currently, this only works for object files, not executables or shared
libraries.

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.

I did this a long time ago with a janky python script, but now
clang-format has built-in support for this. I fed clang-format every
line with a #include and let it re-sort things according to the precise
LLVM rules for include ordering baked into clang-format these days.
I've reverted a number of files where the results of sorting includes
isn't healthy. Either places where we have legacy code relying on
particular include ordering (where possible, I'll fix these separately)
or where we have particular formatting around #include lines that
I didn't want to disturb in this patch.
This patch is *entirely* mechanical. If you get merge conflicts or
anything, just ignore the changes in this patch and run clang-format
over your #include lines in the files.
Sorry for any noise here, but it is important to keep these things
stable. I was seeing an increasing number of patches with irrelevant
re-ordering of #include lines because clang-format was used. This patch
at least isolates that churn, makes it easy to skip when resolving
conflicts, and gets us to a clean baseline (again).

- Kill off begin(), end(), and iterator. It isn't clear what these
mean. Instead provide getBufferStart(), which can be used with
GetNumBytesInBuffer to the same effect.
- Update ComputeColumn to take arguments for the buffer to scan, this
simplifies the implementation of write_impl substantially.
- This should also fix possible problems with the scanning pointer pointing
outside of the current raw_ostream buffer.
