brz.c: Consider _WIN64 for 64-bit pointers too

Browse Source 
The __ia64 and __x86_64__ macros are defined for GCC but not Visual
Studio, but actually this code path should also be taken for Visual
Studio when doing a 64-bit build (x86_64/x64 and aarch64/arm64, _WIN64
will be defined for these cases), since Windows is an LLP64 platform.

This will avoid C4311/C4312 warnings on Visual Studio builds, which are
often warnings of concern as we are dealing with pointers with differing
sizes on 32-bit and 64-bit Windows builds.
