libgcc-std.ver (__clztf2): New.

        * libgcc-std.ver (__clztf2): New.
        (__ctztf2, __popcounttf2, __paritytf2): New.
        * libgcc2.c (__clzSI2, __clzDI2, __ctzSI2, __ctzDI2, __popcountSI2,
        __popcountDI2, __paritySI2, __parityDI2): Use UWmode and UDWmode;
        adjust code to match the different type sizes.
        * libgcc2.h (__clzSI2, __ctzSI2, __popcountSI2, __paritySI2,
        __clzDI2, __ctzDI2, __popcountDI2, __parityDI2): New macros.

        * optabs.c (init_integral_libfuncs): Don't hard-code SImode and
        TImode; select word_mode and twice that.
        (init_floating_libfuncs): Don't hard-code SFmode and TFmode;
        select the modes from float, double, and long double.
        (init_optabs): Remove duplicate initializations.
