LLVM defines `PTHREAD_LIB` which is used by AddLLVM.cmake and various projects to correctly link the threading library when needed. Unfortunately `PTHREAD_LIB` is defined by LLVM's `config-ix.cmake` file which isn't installed and therefore can't be used when configuring out-of-tree builds. This causes such builds to fail since `pthread` isn't being correctly linked. This patch attempts to fix that problem by renaming and exporting `LLVM_PTHREAD_LIB` as part of`LLVMConfig.cmake`. I renamed `PTHREAD_LIB` because It seemed likely to cause collisions with downstream users of `LLVMConfig.cmake`. llvm-svn: 294690
