This is quite silly, but casting to uintptr_t seems like the easiest
option to quiet ubsan.
llvm/lib/Support/xxhash.cpp:107:12: runtime error: applying non-zero offset 8 to null pointer
#0 0x7fe3660404c0 in llvm::xxHash64(llvm::StringRef) llvm/lib/Support/xxhash.cpp:107:12
This patch does the same thing as r338153 for COFF.
Note that this patch affects only the order of log messages.
The output file is already deterministic.

exists in the codebase and is fairly fast.
Patch from Scott Smith!
