optabs.h (enum optab_index): Add new OTI_fmod and OTI_drem.

        * optabs.h (enum optab_index): Add new OTI_fmod and OTI_drem.
        (fmod_optab): Define corresponding macros.
        * optabs.c (init_optabs): Initialize fmod_optab and drem_optab.
        * genopinit.c (optabs): Implement fmod_optab and drem_optab
        using fmod?f3 and drem?f3 patterns.
        * builtins.c (expand_builtin_mathfn_2): Handle BUILT_IN_FMOD{,F,L}
        using fmod_optab and BUILT_IN_DREM{,F,L} using drem_optab.
        (expand_builtin): Expand BUILT_IN_FMOD{,F,L} and
        BUILT_IN_DREM{,F,L} using expand_builtin_mathfn_2 if
        flag_unsafe_math_optimizations is set.

        * reg-stack.c (subst_stack_regs_pat): Handle UNSPEC_FPREM_F,
        UNSPEC_FPREM_U, UNSPEC_FPREM1_F and UNSPEC_FPREM1_U.

        * config/i386/i386.c (ix86_emit_fp_unordered_jump): New function.
        * config/i386/i386-protos.h (ix86_emit_fp_unordered_jump):
        Prototype here.
        * config/i386/i386.md (UNSPEC_FPREM_F, UNSPEC_FPREM_U,
        UNSPEC_FPREM1_F, UNSPEC_FPREM1_U): New unspecs to represent x87's
        fprem and fprem1 instructions.
        (*x86_fnstsw_1): Change input parameter to (reg:CCFP 18).
        Rename insn definition to x86_fnstsw_1.
        (fpremxf4, fprem1xf4): New patterns to implement fprem and fprem1
        x87 instructions.
        (fmodsf3, fmoddf3, fmodxf3): New expanders to implement fmodf, fmod
        and fmodl built-ins as inline x87 intrinsics.
        (dremsf3, dremdf3, dremxf3): New expanders to implement dremf, drem
        and dreml built-ins as inline x87 intrinsics.

        * testsuite/gcc.dg/builtins-40.c: New test.
