Commit 7b38316441a50c2a3f48cd3e5691c85b7234085f by 31459023+hctim

Add LLD to slow builder sanitizer bot.
Bots started spuriously failing this morning because the gcc-built 
bootstrap clang then is used to check-*san. Some of the check-*san 
suites (like check-hwasan) use -fuse-ld=lld in their lit config, and we 
didn't build LLD.
Fix this by building LLD when we build the bootstrap clang.

Commit baaa097360a0e92164119574febcc5613221fa0d by Lang Hames [docs] Fix references to a renamed flag. The -use-mcjit option was replaced with -jit-kind=mcjit a while back. This patch updates the docs to reflect that. Patch by Yu Jian. Thanks Jian!

Commit 20cbb6cdf8b33dd3732b9ef8702e7946b6d8c739 by listmail [LoopPred] Selectively disable to preserve test cases I'm about to enable the new loop predication transform by default. It has the effect of completely destroying many read only loops - which happen to be a super common idiom in our test cases. So as to preserve test coverage of other transforms, disable the new transform where it would cause sharp test coverage regressions. (This is semantically part of the enabling commit. It's committed separate to ease revert if the actual flag flip gets reverted.)

Commit 8748be7750920b7bd669a47be72a81ee7f1d305c by listmail [LoopPred] Enable new transformation by default The basic idea of the transform is to convert variant loop exit conditions into invariant exit conditions by changing the iteration on which the exit is taken when we know that the trip count is unobservable. See the original patch which introduced the code for a more complete explanation. The individual parts of this have been reviewed, the result has been fuzzed, and then further analyzed by hand, but despite all of that, I will not be suprised to see breakage here. If you see problems, please don't hesitate to revert - though please do provide a test case. The most likely class of issues are latent SCEV bugs and without a reduced test case, I'll be essentially stuck on reducing them. (Note: A bunch of tests were opted out of the new transform to preserve coverage. That landed in a previous commit to simplify revert cycles if they turn out to be needed.)

Commit e74e61ff297e81c0a9bda54037033fc40fc76e1d by Saleem Abdulrasool unwind: restore the LINKER_LANGUAGE Have CMake treat the unwind libraries as C libraries rather than C++. There is no C++ runtime dependency at runtime. This ensures that we do not accidentally end up with a link against the C++ runtime. We need to explicitly reset the implicitly linked libraries for C++ to ensure that we do not have CMake force the link against the C++ runtime. This adjustment should enable the NetBSD bots to be happy with this change.

Commit e18f4db208baa84800cf304d7e15f2ee7343cd05 by shafik [LLDB] Adding caching to libc++ std::function formatter for lookups that require scanning symbols Performance issues lead to the libc++ std::function formatter to be disabled. This change is the first of two changes that should address the performance issues and allow us to enable the formatter again. In some cases we end up scanning the symbol table for the callable wrapped by std::function for those cases we will now cache the results and used the cache in subsequent look-ups. This still leaves a large cost for the initial lookup which will be addressed in the next change. Differential Revision: https://reviews.llvm.org/D67111

Commit ba1dfae054b4c9a8b11aabd62fd0dcb792366206 by aktoon Keep import function list for inlinee profile update Summary: When adjusting function entry counts after inlining, Funciton::setEntryCount is called without providing an import function list. The side effect of that is the previously set import function list will be dropped. The import function list is used by ThinLTO to help import hot cross module callee for LTO inlining, so dropping that during ThinLTO pre-link may adversely affect LTO inlining. The fix is to keep the list while updating entry counts for inlining.
