Herman S. 3efc88abbb [Base] Fix math.h portability: use __builtin_ffs and fix lzcnt narrowing ...

ffs() can collide with POSIX macro definitions on some platforms;
__builtin_ffs is the portable GCC/Clang intrinsic. log2_floor/log2_ceil
passed template types directly to lzcnt which has only uint32_t and
uint64_t overloads, causing implicit narrowing on smaller types.
