i386.c (ix86_expand_branch, [...]): Handle TImode in 64-bit mode the same as DImode in 32-bit mode.

gcc/
2005-07-18  Jan Beulich  <jbeulich@novell.com>

	* config/i386/i386.c (ix86_expand_branch, ix86_expand_setcc,
	ix86_expand_carry_flag_compare, ix86_expand_int_movcc): Handle TImode
	in 64-bit mode the same as DImode in 32-bit mode.
	(ix86_expand_ashl_const, ix86_split_ashl, ix86_split_ashr,
	ix86_split_lshr): Likewise. Rename to no longer refer to a specific
	mode. Add new mode parameter.
	* config/i386/i386.h (CONST_OK_FOR_LETTER_P): Describe and handle 'O'.
	* config/i386/i386.md (cmpti, addti3, subti3, negti2, ashlti3, ashrti3,
	x86_64_shift_adj): New expanders.
	(*addti3_1, *subti3_1, *negti2_1, ashlti3_1, *ashlti3_2, ashrti3_1,
	*ashrti3_2, lshrti3_1, *lshrti3_2, x86_64_shld, x86_64_shrd): New
	insns.
	Respective new splitters. Use renamed shift splitter helpers in 32-bit
	DImode shift splitters.
	* config/i386/i386-protos.h (ix86_split_ashl, ix86_split_ashr,
	ix86_split_lshr): Renamed from ix86_split_[al]sh[rl]di. Added new
