Building with BUILD_SHARED_LIBS makes it tricky to copy around
executables at will, since they won't be able to find the LLVM
libraries any more. This makes testing a feature that's based on the
executable name problematic, so we'll just disable these two tests in
that configuration.
We could potentially fix this by symlinking the lib directory into the
test directory, but that wouldn't work on windows, and losing testing
on windows would be far worse than losing testing on a configuration
that's barely even supported.

AArch64 with GlobalISel enabled, or fuzzer=x86_64 to fuzz x86, with no

Note that this handrolls a subset of cl::opts to recognize, rather

Summary:
This suppresses the generation of .Lcfi labels in our textual assembler.
It was annoying that this generated cascading .Lcfi labels:
llc foo.ll -o - | llvm-mc | llvm-mc
After three trips through MCAsmStreamer, we'd have three labels in the
output when none are necessary. We should only bother creating the
labels and frame data when making a real object file.
This supercedes D38605, which moved the entire .seh_ implementation into
MCObjectStreamer.
This has the advantage that we do more checking when emitting textual
assembly, as a minor efficiency cost. Outputting textual assembly is not
performance critical, so this shouldn't matter.

This allows the escape sequences (\a, \n, \r, \t, \\, \x[0-9a-f]*,
\[0-7]*, "") to appear in .rc scripts. These are parsed and output in
the same way as it's done in original MS implementation.
The way these sequences are processed depends on the type of the
resource it resides in, and on whether the user declared the string to
be "wide" or "narrow".
I tried to maintain the maximum compatibility with the original tool
(and fail in some erroneous situations that are accepted by .rc).
However, there are some (extremely rare) cases where Microsoft tool
outputs nonsense. I found it infeasible to detect such casses.

This is part 6 of llvm-rc serialization.
This adds ability to output cursors and icons as resources.
Unfortunately, we can't just copy .cur or .ico files to output - as each
file might contain multiple images, each of them needs to be unpacked
and stored as a separate resource. This forces us to parse cursor and
icon contents. (Fortunately, these formats are pretty similar and can be
processed by mostly common code).
As test files are binary, here is a short explanation of .cur and .ico
files stored:
cursor.cur, cursor-8.cur, cursor-32.cur are sample correct cursor files,
differing in their bit depth.
icon-old.ico, icon-new.ico are sample correct icon files;
icon-png.ico is a sample correct icon file in PNG format (instead of
usual BMP);
cursor-eof.cur is an incorrect cursor file - this is cursor.cur with
some of its final bytes removed.
cursor-bad-offset.cur is an incorrect cursor file - image header states
that image data begins at offset 0xFFFFFFFF.
Sample correct cursors and icons were created by Nico Weber.

At the last LLVM dev meeting we had a debug info for optimized code
BoF session. In that session I presented some graphs that showed how
the quality of the debug info produced by LLVM changed over the last
couple of years. This is a cleaned up version of the patch I used to
collect the this data. It is implemented as an extension of
llvm-dwarfdump, adding a new --statistics option. The intended
use-case is to automatically run this on the debug info produced by,
e.g., our bots, to identify eyebrow-raising changes or regressions
introduced by new transformations that we could act on.
In the current form, two kinds of data are being collected:
- The number of variables that have a debug location versus the number
of variables in total (this takes into account inlined instances of
the same function, so if a variable is completely missing form only
one instance it will be found).
- The PC range covered by variable location descriptions versus the PC
range of all variables' containing lexical scopes.
The output format is versioned and extensible, so I'm looking forward
to both bug fixes and ideas for other data that would be interesting
to track.

Somehow a few massive errors slipped though the cracks of testing.
1. The code in Segment::finalize was left over from the old layout
algorithm. In certain situations this would cause very strange issues
with segment layout. For instance in the shift-segments.test case it
would cause the second segment to have the same offset as the first.
2. In debugging this I discovered another issue. Namely section alignment
was not being computed based on Section->Align but instead
Section->Offset which is bizarre and makes no sense. I have no clue how
it worked in the first place. This issue is also fixed
3. Fixing #2 exposed a bug where things were not being written past the end
of the file that technically should have been. This was because in
certain cases (like overlapping-segments) the end of the file wouldn't
always be bumped if the offset could be chosen relative to an existing
segment that already had it's offset chosen. For fully nested segments
this is fine but for overlapping segments this leaves the end of the
file short. So I changed how the offset is bumped when looping though
segments.
