Added files:

Log message:
	* 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.
