Original message:
Rather than rolling our own functions to read little endian data
from a buffer, we can use the support in llvm's Endian.h.
No functional change.

Turns out debug_frame does use multiple fragments, so it doesn't
compress correctly with the current approach. Disable compressing it for
now while I figure out what's the best solution for it.

WinCOFF cannot form PC relative relocations to support absolute
MCValues. We should reenable this once WinCOFF supports emission of
IMAGE_REL_I386_REL32 relocations.
This fixes PR19272.

This is a bit of a stab in the dark, since I have zlib on my machine.
Just going to bounce it off the bots & see if it sticks.
Do we have some convention for negative REQUIRES: checks? Or do I just
need to add a feature like I've done here?

The test was failing because clang-cl changes the default triple
to target MSVC-style Win32. This is kind of wonky, but hasn't been
a problem until we started warning:
warning: unknown platform, assuming -mfloat-abi=soft
Some of the tests in cl-options.c were running with -Werror, causing them
to fail.
Fixing this by FileCheck-ifying those tests instead of using -Werror.

condition where we could end up killing debugserver (and thus the target) before it had a chance
to detach.
Also fix debugserver to send the OK AFTER it detaches to avoid the same race condition.

v2[fi]64 values need to be explicitly passed in VSX registers. This is because
the code in TRI that finds the minimal register class given a register and a
value type will assert if given an Altivec register and a non-Altivec type.

Response file is a command line argument in the form of @file. The GNU-
compatible driver expands the file contents, replacing @file argument.

It was using "lc -filetype=obj" just to pass the result to
"llvm-objdupm -disassemble" and then filecheck assembly.
The CHECK-NOT would never match anyway since it was missing $.

This patch is to support --defsym option for ELF file format/GNU-compatible
driver. Currently it takes a symbol name followed by '=' and a number. If such
option is given, the driver sets up an absolute symbol with the specified
address. You can specify multiple --defsym options to define multiple symbols.
GNU LD's --defsym provides many more features. For example, it allows users to
specify another symbol name instead of a number to define a symbol alias, or it
even allows a symbol plus an offset (e.g. --defsym=foo+3) to define symbol-
relative alias. This patch does not support that, but will be supported in
subsequent patches.

-Wselector-type-mismatch default again. After
internal discussions, we think that in most cases
it has helped our developers find hard to detect
undefined behaviors. We are going to provide a syntax
(and fix-it) to suppress the warning in remaining of
false positive cases.

-u behaviour is apparently not portable between linkers (see cfe-commits
discussions for r204379 and r205012). I've moved the logic to IRGen,
where it should have been in the first place.
I don't have a Linux system to test this on, so it's possible this logic
*still* doesn't pull in the instrumented profiling runtime on Linux.
I'm in the process of getting tests going on the compiler-rt side
(llvm-commits "[PATCH] InstrProf: Add initial compiler-rt test"). Once
we have tests for the full flow there, the runtime logic should get a
whole lot less brittle.

The non-SJLJ and SJLJ intrinsics are generated by the frontend and
