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.
661c8bb gallium/util: Don't implement u_bit_scan64 on MSVC.
