handle TFmodes.
(print_operand, ix86_expand_branch, ix86_expand_fp_movcc): Handle
TFmodes.
(ix86_split_long_move): Use number of part returned
by ix86_split_to_parts
* i386.h (MASK_128BIT_LONG_DOUBLE, TARGET_128BIT_LONG_DOUBLE):
New macros.
(TARGET_SWITCHES): Add 128bit-long-double and 96bit-long-double
(LONG_DOUBLE_TYPE_SIZE): Change from constant.
(MAX_LONG_DOUBLE_TYPE_SIZE): New macro.
(INTEL_EXTENDED_IEEE_FORMAT): Likewise.
(ALIGN_MODE_128): Add TFmode.
(IS_STACK_MODE): Likewise.
(HARD_REGNO_NREGS): TFmode needs 3 registers.
(HARD_REGNO_OK): Support TFmodes.
(ASM_OUTPUT_LONG_DOUBLE): Handle TFmodes.
* i386.md (scheduler definitions): Use memory operand to determine
fst/fld instructions; use mode attribute to determine real mode of
the instruction.
(*tf): New patterns, expanders and splitters; based on XFmode patterns.
