gallium/util: Don't implement u_bit_scan64 on MSVC.

Browse source 
As ffsll doesn't exist in MSVC yet, and u_bit_scan64 is only used by
radeonsi which is never built with MSVC.

This is just a stop-gap fix to unbreak MSVC build until we refactor these
mathematical portability wrappers into src/util.

Trivial.
