mesa: remove _mesa_ffs(), implement ffs() for non-GNU platforms
Call ffs() and ffsll() everywhere. Define our own ffs(), ffsll() functions when the platform doesn't have them. v2: remove #ifdef _WIN32, __IBMC__, __IBMCPP_ tests inside ffs() implementation. The #else clause was recursive. Reviewed-by: Kenneth Graunke <[email protected]> Tested-by: Alexander von Gluck <[email protected]>
