Don't use _BitScanForward64/_BitScanReverse64 on 32-bit MSVC builds
677319746 added support for making use of MSVC's bit scanning functions.
However, that commit failed to consider 32-bit MSVC builds where the
64-bit versions of these functions are unavailable. This resulted in
compilation failures on 32-bit MSVC.
Here we adjust the code so we fall back on the manual way of finding the
bit positions for 64-bit integers when building on 32-bit MSVC.
