Fix PR gcov-profile/55734 by using methods from hwint.c instead of
builtins, to handle non-GCC and older versions of GCC. When building
libgcov.a, however, hwint.c is not available, but we are always using
the bootstrapped compiler and can therefore use the builtins.

Use __builtin_popcount instead of __builtin_popcountll, since we
are operating on an int.

Use floor_log2 directly, instead of clz_hwi for the non-libgcov case,
and handle situations where the size of the gcov_type is bigger than
HOST_WIDE_INT. Verified that the various cases compiled by forcing
different HOST_BITS_PER_WIDE_INT values.
