clang-cl.
I noticed this because the inclusion was cased incorrectly (Intrin.h
instead of intrin.h), which when cross-compiling on a case sensitive
file system would cause the intrin.h from the Windows SDK to be included
(which LLVM can't handle) instead of the one from clang's resource

Regex out the local hash comparison test.
Since the local hash is a different number of bytes depending
on host architecture, we don't have a consistent value. I
