	* builtins.c (expand_builtin_mathfn): Handle BUILT_IN_RINT{,F,L}
	using rint_optab.
	(expand_builtin): Expand BUILT_IN_RINT{,F,L} using
	expand_builtin_mathfn.
	* genopinit.c (optabs): Rename trunc_optab to btrunc_optab. Use
	btrunc?f patterns for btrunc_optab. Implement rint_optab using
	rint?f patterns.
	* optabs.c (init_optabs): Initialize rint_optab.
	* optabs.h (enum optab_index): Rename OTI_trunc to OTI_btrunc.
	Add new OTI_rint.
	(btrunc_optab): Rename macro from trunc_optab.
	(rint_optab): Define corresponding macro.
	
	* reg-stack.c (subst_stack_regs_pat): Handle UNSPEC_FRNDINT_FLOOR,
	UNSPEC_FRNDINT_CEIL, UNSPEC_FRNDINT_TRUNC, UNSPEC_FRNDINT_MASK_PM.
	
	* config/i386/i386-protos.h (emit_i387_cw_initialization):
	Change prototype. Add new int parameter.
	* config/i386/i386.c (emit_i387_cw_initialization):
	Handle new rounding modes.
	
	* config/i386/i386.h (enum fp_cw_mode): Delete.
	(MODE_NEEDED): Handle new rounding modes.
	(EMIT_MODE_SET): Change condition to handle new rounding modes.
	
	* config/i386/i386.md (UNSPEC_FRNDINT_FLOOR, UNSPEC_FRNDINT_CEIL,
	UNSPEC_FRNDINT_TRUNC, UNSPEC_FRNDINT_MASK_PM): New unspecs to
	represent different rounding modes of frndint insn.
	(type): Add frndint type.
	(i387, length, memory): Handle this type.
	(i387_cw): New attribute definition.
	(*fix_truncdi_1, fix_truncdi_nomemory, fix_truncdi_memory,
	*fix_truncsi_1, fix_truncsi_nomemory, fix_truncsi_memory,
	*fix_trunchi_1, fix_trunchi_nomemory, fix_trunchi_memory):
	Add "i387_cw" attribute defined to "trunc".
	(x86_fnstcw_1): Remove comment.
	(*frndintxf2): Rename insn definition to frndintxf2. Move
	insn definition near rint?f2 expanders.
	(rintdf2, rintsf2, rintxf2): New expanders to implement rint,
	rintf and rintl built-ins as inline x87 intrinsics.
	(frndintxf2_floor): New pattern to implement floor rounding
	mode with frndint x87 instruction.
	(floordf2, floorsf2, floorxf2): New expanders to implement floor,
	floorf and floorl built-ins as inline x87 intrinsics.
	(frndintxf2_ceil): New pattern to implement ceil rounding
	mode with frndint x87 instruction.
	(ceildf2, ceilsf2, ceilxf2): New expanders to implement ceil,
	ceilf and ceill built-ins as inline x87 intrinsics.
	(frndintxf2_trunc): New pattern to implement trunc rounding
	mode with frndint x87 instruction.
	(btruncdf2, btruncsf2, btruncxf2): New expanders to implement trunc,
	truncf and truncl built-ins as inline x87 intrinsics.
	(frndintxf2_mask_pm): New pattern to implement rounding
	mode with exceptions with frndint x87 instruction.
	(nearbyintdf2, nearbyintsf2, nearbyintxf2): New expanders to
	implement nearbyint, nearbyintf and nearbyintl built-ins as
	inline x87 intrinsics.
	
	* testsuite/gcc.dg/builtins-46.c: New.
