Argyrios Kyrtzidis e9012b035c For CrashRecoveryContext::RunSafelyOnThread, propagate Darwin's PRIO_DARWIN_BG to the new thread if it is
set on the calling thread.

This allows libclang's indexing threads to propagate their priority to the clang module building threads.

JF Bastien 144829d3e9 Random Number Generator (llvm)
Provides an abstraction for a random number generator (RNG) that produces a stream of pseudo-random numbers.
The current implementation uses C++11 facilities and is therefore not cryptographically secure.

The RNG is salted with the text of the current command line invocation.
In addition, a user may specify a seed (reproducible builds).

In clang, the seed can be set via

-frandom-seed=X
In the back end, the seed can be set via

-rng-seed=X
This is the llvm part of the patch.

Daniel Sanders e8b1f91afb Revert: r211588 - [mips] Use __clear_cache builtin instead of cacheflush() in Unix Memory::InvalidateInstructionCache()
Buildbot reports a test failure on the llvm-mips-linux builder and blames r211588.
Although it doesn't appear in the blamelist, it seems it could also be r211587
(because it's committed to compiler-rt?) since they were tested together.

Reverting the most likely suspect (r211588) to confirm one way or the other.

David Blaikie 16a9eab399 Recommit 211309 (StringMap::insert), reverted in 211328 due to issues with private, but non-deleted, move members.
Certain versions of GCC (~4.7) couldn't handle the SFINAE on access
control, but with "= delete" (hidden behind a macro for portability)
this issue is worked around/addressed.

Zachary Turner 6ad2444d5b Kill the LLVM global lock.
This patch removes the LLVM global lock, and updates all existing
users of the global lock to use their own mutex.    None of the
existing users of the global lock were protecting code that was
mutually exclusive with any of the other users of the global
lock, so its purpose was not being met.

Rafael Espindola 2a826e40fa Finishing touch for the std::error_code transition.
While std::error_code itself seems to work OK in all platforms, there
are few annoying differences with regards to the std::errc enumeration.

This patch adds a simple llvm enumeration, which will hopefully avoid build
breakages in other platforms and surprises as we get more uses of
std::error_code.
