generic: implement __fls on all 64-bit archs
Implement __fls on all 64-bit archs: alpha has an implementation of fls64. Added __fls(x) = fls64(x) - 1. ia64 has fls, but not __fls. Added __fls based on code of fls. mips and powerpc have __ilog2, which is the same as __fls. Added __fls = __ilog2. parisc, s390, sh and sparc64: Include generic __fls. x86_64 already has __fls.
