This revision adds noread_thread_id attribute to intrinsics, including:
(2) memset, memcpy, ...
(3) debugging intrinsics
Also the patch removes llvm.threadlocal.address(ptr) and llvm.thread.pointer() from DefaultAttributeIntrinsics since they may access the thread identification.
I am not 100% sure I added noread_thread_id attribute for all the proper intrinsics. But I think it is not bad to add them in an iterative fashion.
