Zachary Turner 529e9d307e Remove support for runtime multi-threading. ... This patch removes the functions llvm_start_multithreaded() and llvm_stop_multithreaded(), and changes llvm_is_multithreaded() to return a constant value based on the value of the compile-time definition LLVM_ENABLE_THREADS. Previously, it was possible to have compile-time support for threads on, and runtime support for threads off, in which case certain mutexes were not allocated or ever acquired. Now, if the build is created with threads enabled, mutexes are always acquired. A test before/after patch of compiling a very large TU showed no noticeable performance impact of this change.
