Many things were broken:
- We stopped building most builtins on Windows in r261432 for reasons
that are not at all clear to me. This essentially reverts that patch.
- Fix %librt to expand to clang_rt.builtins-$arch.lib on Windows instead
of libclang_rt.builtins-$arch.a.
- Fix memory protection tests (trampoline, enable executable, clear
cache) on Windows. One issue was that the MSVC incremental linker
generates ILT thunks for functions with external linkage, so memcpying
the functions into the executable stack buffer wasn't working. You
can't memcpy an RIP-relative jump without fixing up the offset.
- Disable tests that rely on C99 complex library functions when using
the MSVC CRT, which isn't compatible with clang's C99 _Complex.
In theory, these could all be separate patches, but it would not green
the tests, so let's try for it all at once. Hopefully this fixes the
clang-x64-ninja-win7 bot.
llvm-svn: 299780
Summary:
Originally, a few tests fail for armhf target due to:
1) COMPILER_RT_ARMHF_TARGET was not set when building the lib
2) COMPILER_RT_ABI should not be defined as `__attribute__((pcs("aapcs")))` for armhf when building for both lib and tests

mulsc3_test.c is a newly exposed issue, which will be addressed separately.

Re-land of r298714 which got reverted in r298868.
It looks like the current lit tests won't run for Apple.
Possible reason is the libname is different. (need to update
the base_lib variable of lit.cfg)

Summary:
Original r297566 (https://reviews.llvm.org/D30802) is splitted into two parts.
This part adds CMakefile/lit.cfg support.

Summary:
This patch implements a initial support of lit test for builtins.
Unit/arm/call_apsr.S is updated to support thumb1.
It also fixes a bug in arm/aeabi_uldivmod_test.c
gcc_personality_test is XFAILED as the framework cannot handle it so far.
cpu_model_test is also XFAILED for now as it is expected to return non-zero.

This predicate compares the host's marketing OS version to one passed as
argument. Currently, only darwin targets are supported. This is done by parsing
the SystemVersion.plist file.
Also added in this patch is some lit testing infrastructure for builtins, which
previously had none. This part of the patch was written by Alex Lorenz (with
some minor modifications).
This patch is part of a feature I proposed here:
