mingw gcc sets the macro _M_IX86 which is normally only set
by Visual C and clangcl which are Visual C style source code
style for assembly, but gcc is not Visual C compatible.
Add _MSC_VER to most ifdefs to detect that its really Visual C
or clangcl and not mingw gcc so the gcc source code will be used.

The low level hamming distance functions have size limitations
based on counter sizes.  The higher level calls the low level
in blocks that avoid overflow and then accumulators in int64.
This test compares the results of the low levels to the high
level and against a known value (all ones) to ensure the
count is correct for any specified size.
The the size is very large, the result is expected to be
different.
