Christophe Lyon 5143faee0d libgcc: use __builtin_clz and __builtin_ctz in libbid 
This patch replaces libbid's implementations of clz and ctz for 32 and
64 bits inputs which used several masks, and switches to the
corresponding builtins. This will provide a better implementation,
especially on targets with clz/ctz instructions.
