Before this patch...

Before this patch, function multiversioning determines that two functions
are different by comparing the arch type and isa flags that are set
after the target string is processed. This leads to cases where  the
versions become identical when the command-line target options are
altered.

This patch modifies the function version determination to
just compare the target string.

Fix PR gcov-profile/55734 by using methods from hwint.c instead of builtins...

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.
