llvm: updated to 7.0.0

LLVM 7.0.0 Release

The release contains the work on trunk up to SVN revision 338536 plus
work on the release branch. It is the result of the community's work
over the past six months, including: function multiversioning in Clang
with the 'target' attribute for ELF-based x86/x86_64 targets, improved
PCH support in clang-cl, preliminary DWARF v5 support, basic support
for OpenMP 4.5 offloading to NVPTX, OpenCL C++ support, MSan, X-Ray
and libFuzzer support for FreeBSD, early UBSan, X-Ray and libFuzzer
support for OpenBSD, UBSan checks for implicit conversions, many
long-tail compatibility issues fixed in lld which is now production
ready for ELF, COFF and MinGW, new tools llvm-exegesis, llvm-mca and
diagtool. And as usual, many optimizations, improved diagnostics, and
bug fixes.

 Don't use non-portable -z discard-unused on SunOS.
+On Darwin, create symbolic links to shared libraries.
 On Darwin, use correct install-name for shared libraries.
