Refactor the DetectDistro() function to take a single vfs::FileSystem
reference only, instead of Driver and llvm::Triple::ArchType.
The ArchType parameter was not used anyway, and Driver was only used to
obtain the VFS.
Aside to making the API simpler and more transparent, it makes it
easier to add unit tests for the function in the future -- since
the tests would need only to provide an appropriate VFS.

System utilities such as atos only support DWARF 4 on OS X 10.11+ and

has a recent enough operating system version and use DWARF 2 for older
systems.

These were reverted in r283753 and r283747.
The first patch added a header to the root 'Headers' install directory,
instead of into 'Headers/cuda_wrappers'. This was fixed in the second
patch, but by then the damage was done: The bad header stayed in the
'Headers' directory, continuing to break the build.
We reverted both patches in an attempt to fix things, but that still
didn't get rid of the header, so the Windows boostrap build remained
broken.
It's probably worth fixing up our cmake logic to remove things from the
install dirs, but in the meantime, re-land these patches, since we
believe they no longer have this bug.

Unfortunately we can't enable it for all N64 because it is not yet possible to
distinguish N32 from N64 from the triple on other environments.
N64 has been confirmed to produce identical (within reason) objects to GAS
during stage 2 of compiler recursion on N64-abi Fedora. Unfortunately,
Fedora's triples do not distinguish N32 from N64 so I can't enable it by
default there. I'm currently repeating this testing for Debian mips64el but
it's very unlikely to produce a different result.

iOS (and other 32-bit ARM variants) always require a valid frame pointer to
improve backtraces. Previously the -fomit-frame-pointer and
-momit-leaf-frame-pointer options were being silently discarded via hacks in
the backend. It's better if Clang configures itself to emit the correct IR and
warns about (ignored) attempts to override this.

Summary:
The eprintf library was added before the general OS X builtins library existed as a place to store one builtin function. Since we have for several years had an actual mandated builtin library for OS X > 10.5, we should just merge eprintf into the main library.
This change will resolve PR28855.
As a follow up I'll also patch compiler-rt to not generate the eprintf library anymore.

Bug 1: triples like armv7-pc-linux-musl use the wrong linker name
ld-musl-armv7.so.1; the right name should be ld-musl-arm.so.1, disregarding the
subarch field.
Bug 2: when compiler option -mhard-float is used, we should use the "hardfloat"
linker, no matter whether the triple itself mentions "hardfloat".

Compute an effective triple once per job. Cache the triple in the
prevailing ToolChain for the duration of the job.
Clients which need effective triples now look them up in the ToolChain.
This eliminates wasteful re-computation of effective triples (e.g in
getARMFloatABI()).
While we're at it, delete MachO::ComputeEffectiveClangTriple. It was a
no-op override.

This patch introduces a new cmake variable: CLANG_DEFAULT_RTLIB, thru
which we can specify a default value for -rtlib (libgcc or
compiler-rt) at build time, just like how we set the default C++
stdlib thru CLANG_DEFAULT_CXX_STDLIB.
With these two options, we can configure clang to build binaries on
Linux that have no runtime dependence on any gcc libs (libstdc++ or
libgcc_s).

Driver: Stop linking to C++ when using sanitizers on Darwin
Sanitizers on Darwin are built as dynamic libraries, not static libraries.
Sanitizers will have their C++ dependency satisfied internally (LC_LOAD_DYLIB)
in the libclang_rt dylib. As long as the sanitizers stay dynamic and not static,
linking against C++ when enabling a sanitizer becomes over linkage.

The two patches together enable clang to support targets like

glibc. This make it easy for clang to work on some musl-based systems

We now have a cmake option to change the default: ENABLE_LINKER_BUILD_ID.
The reason is that build-id is fairly expensive, so we shouldn't impose
it in the regular edit/build cycle.
This is similar to gcc, that has an off by default --enable-linker-build-id
option.
