9610a42e59 [CMake] Provide the ability to skip stripping when generating dSYMs
For debugging it is useful to be able to generate dSYM files but not strip the executables. This change adds the ability to skip stripping by setting LLVM_EXTERNALIZE_DEBUGINFO_SKIP_STRIP=On.

db91435d44 [cmake] Add -fms-compatibility-version=19 when clang-cl gives errors about char16_t
What we are really trying to do here is to figure out if we are using
the 2015 STL. Unfortunately, so far as I know the MSVC STL does not
define a version macro that we can check directly. Instead I wrote a
check to see if char16_t works.

that the standalone build of Clang still gets the compiler version

f801d8b322 cmake: Simplify the iOS.cmake toolchain
- Remove a comment that was clearly copy pasted from Android.cmake and
  isn't relevant.
- Remove the toolchain's sensitivity to the environment. It's less
  error prone to just allow users to set CMAKE_OSX_SYSROOT if they
  want to use a custom SDK.
- Stop explicitly setting -mios-version-min to the default value. It
  just adds needless complexity.

This makes building the native tablegen work for me even when SDKROOT
is set in the environment (or passed in as -DCMAKE_OSX_SYSROOT).

575b993830 Disable MSVC 2015's warning about zero extending after ~ and others
Very often in LLVM we have APIs that take a bitwidth and a uint64_t that
we pass immediates such as ~0U to. Consider APInt, Constant, and
MachineInstrBuilder::addImm. Fixing all uses of these APIs to manually
extend their arguments to uint64_t doesn't seem worth it.

cf2a93b691 Strip local symbols when using externalized debug info.
When we build LLVM with externalized debug info, all debugging and
symbolication related data is extracted into dSYM files prior to
stripping. As such, there is no need to preserve local symbols in LLVM
binaries after dSYM creation.

This shrinks libLLVM.dylib from 58MB to 55MB on my system.

93083d4986 tools/llvm-config: improve shared library support
Summary:

This is a re-commit of r257003, which was reverted,
along with the fixes from http://reviews.llvm.org/D15986.

r252532 added support for reporting the monolithic library
when LLVM_BUILD_LLVM_DYLIB is used. This would only be done
if the individual components were not found, and the dynamic
library is found.

This diff extends this as follows:
 - If LLVM_LINK_LLVM_DYLIB is set, then prefer the shared
   library, even if all component libraries exist.
 - Two flags, --link-shared and --link-static are introduced
   to provide explicit guidance. If --link-shared is passed
   and the shared library does not exist, an error results.

Additionally, changed the expected shared library names from
(e.g.) LLVM-3.8.0 to LLVM-3.8. The former exists only in an
installation (and then only in CMake builds I think?), and not
in the build tree; this breaks usage of llvm-config during
builds, e.g. by llvm-go.

73c7b058de [cmake] Fix add_version_info_from_vcs git svn version bug.
Summary:
add_version_info_from_vcs was setting SVN_REVISION to the last fetched
svn revision when using git svn instead of the svn revision
corresponding to HEAD.  This leads to conflicts with the definition of
SVN_REVISION in SVNVersion.inc generated by GetSVN.cmake when HEAD is
not the most recently fetched svn revision.

Use 'git svn info' to determine SVN_REVISION when git svn is being used
instead (as is done in GetSVN.cmake).

d8f6d5cdd7 Make WinCOFFObjectWriter.cpp's timestamp writing not use ENABLE_TIMESTAMPS
LLVM_ENABLE_TIMESTAMPS controls if timestamps are embedded into llvm's
binaries. Turning it off is useful for deterministic builds.

r246905 made it so that the define suddenly also controls if the binaries that
the llvm binaries _create_ embed timestamps or not – but this shouldn't be a
configure-time option. r256203/r256204 added a driver option to toggle this on
and off, so this patch now passes this driver option in LLVM_ENABLE_TIMESTAMPS
builds so that if LLVM_ENABLE_TIMESTAMPS is set, the build of LLVM is
deterministic – but the built clang can still write timestamps into other
executables when requested.

This also allows removing some of the test machinery added in r292012 to work
around this problem.

See PR24740 for background.

c4724f60d7 Silence all C4592 warnings with MSVC 2015 Update 1. This warning produces false positives that Microsoft says will be fixed in Update 2. Until this produces reliable diagnostics, it is safe to disable the diagnostic -- the compiler is not doing anything different than it previously did aside from issuing the diagnostic.
(Note, this silences at least one false positive in LLVM with FeatureBitset uses.)

1b6b889f9c Fix non-PIC build after 253959
CMAKE_EXE_LINKER_FLAGS is a string. Appending a flag using list(APPEND) introduces an extra
semicolon which breaks stuff. Change this to append the value in the same way that everyone else
seems to be doing.

f92fdc8e93 [CMake] When disabling PIC, also pass -fno-pie when linking if it is supported.
Building clang with -fno-pie generates slightly faster code. In my not-very-rigorous testing I saw about a 4% speed up using the clang test-suite sources.

b856f91ff4 [CMake] export_executable_symbols also needs to add -rdynamic to the linker flags on Darwin
Without -rdynamic LLVM built with LTO fails to pass "check" due to loadable modules failing.
