Log message:

	* builtins.c: Implement support for sincos function.
	(expand_builtin_mathfn): Remove BUILT_IN_SIN{,F,L} and
	BUILT_IN_COS{,F,L}.
	(expand_builtin_mathfn_3): New function.
	(expand_builtin): Expand BUILT_IN_SIN{,F,L} and
	BUILT_IN_COS{,F,L} using expand_builtin_mathfn_3 if
	flag_unsafe_math_optimization is set.
	
	* optabs.h (enum optab_index): Add new OTI_sincos.
	(sincos_optab): Define corresponding macro.
	
	* optabs.c (init_optabs): Initialize sincos_optab.
	(expand_twoval_unop): New function.
	
	* genopinit.c (optabs): Implement sincos_optab using sincos?f3
	patterns.
	
	* reg-stack.c (subst_stack_regs_pat): Handle UNSPEC_SINCOS_COS
	and UNSPEC_SINCOS_SIN.
	
	* config/i386/i386.md (sincosdf3, sincossf3, *sincosextendsfdf3,
	sincosxf3): New patterns to implement sincos, sincosf and sincosl
	built-ins as inline x87 intrinsics. Define splits for
	sindf2, sinsf2, *sinextendsfdf2, sinxf2, cosdf2,
	cossf2, *cosextendsfdf2 and cosxf2 patterns from corresponding
	sincos patterns.
	(sindf2, sinsf2, sinxf2): Rename to *sindf2, *sinsf2, *sinxf2.
	(cosdf2, cossf2, cosxf2): Rename to *cosdf2, *cossf2, *cosxf2.
	
	(UNSPEC_SINCOS_SIN, UNPEC_SINCOS_COS): New unspecs to represent
	x87's unspec insn.
	
	* gcc.dg/builtins-36.c: New test.
