libgcc2.c (__ffsdi2, [...]): Change return type to "int".

        * libgcc2.c (__ffsdi2, __clzsi2, __clzdi2, __ctzsi2, __ctzdi2,
        __popcountsi2, __popcountdi2, __paritysi2, __paritydi2): Change
        return type to "int".  Shuffle declarations and undef int trap.
        * libgcc2.h: Remove their declarations.
        * optabs.c (expand_unop): Force outmode to int for bitops.
