  Log Message:
  -----------
  [Reland][ADT][ConcurrentHashTable] adapt ConcurrentHashTable and its users to LLVM_ENABLE_THREADS=0 mode.

This patch hides thread specific handling under LLVM_ENABLE_THREADS guard.
It also removes usages of thread_local variables, since it has a weak
support on some platforms. Instead, the patch uses single mutex for locking
allocator. That may be replaced with more effective allocator later.
