5e6f018471 Add SVN version to libLLVMLTO
Summary: For Incremental LTO, we need to make sure that an old
cache entry is not used when incrementally re-linking with a new
libLTO.
Adding a global LLVM_REVISION in llvm-config.h would for to
rebuild/relink the world for every "git pull"/"svn update".
So instead only libLTO is made dependent on the VCS and will
be rebuilt (and the dependent binaries relinked, i.e. as of
today: libLTO.dylib and llvm-lto).

9fcc64726a Replace hardcoded comment at 'lit.site.cfg.in'
At the moment almost every lit.site.cfg.in contains two lines comment:

## Autogenerated by LLVM/Clang configuration.
# Do not edit!

The patch adds variable LIT_SITE_CFG_IN_HEADER, that is replaced from 
configure_lit_site_cfg with the note and some useful information.

c8f9cc971a Update and fix LLVM_ENABLE_MODULES:
1) We need to add this flag prior to adding any other, in case the user has
specified a -fmodule-cache-path= flag in their custom CXXFLAGS. Such a flag
causes -Werror builds to fail, and thus all config checks fail, until we add
the corresponding -fmodules flag. The modules selfhost bot does this, for
instance.

2) Delete module maps that were putting .cpp files into modules.

3) Enable -fmodules-local-submodule-visibility, to get proper module
visibility rules applied across submodules of the same module. Disable
-fmodules for C builds, since that flag is not available there.

918b321130 [CMake] Make llvm_ExternalProject always call the build action
This makes it so that when running 'ninja test-suite' from the top-level LLVM ninja build it *always* re-runs the ninja command in the test-suite directory.

This mechanism is required because the top-level ninja file doesn't have a view into the subdirectory dependency tree, so it can't know what, if anything, needs to be rebuilt.

dec93a4fca 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).

0249db6d41 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.

On some distributions (e. g. Exherbo), a package can be installed for several

28c07122cf 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.

e690f5b8b2 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.

40581de42f [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).

f2a28338f0 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.
