* reg-stack.c (subst_stack_regs_pat): Handle <UNSPEC_FIST_FLOOR> and
<UNSPEC_FIST_CEIL> case.
* config/i386/i386.md (UNSPEC_FIST_FLOOR, UNSPEC_FIST_CEIL): New.
(*fist<mode>2_floor_1, fistdi2_floor, fistdi2_floor_with_temp)
(fist<mode>2_floor, fist<mode>2_floor_with_temp): New isns patterns
to implement lfloor and llfloor built-ins as x87 intrinsic function.
(fistdi2_floor, fist<mode>2_floor splitters): New splitters.
(lfloor<mode>2): New expanders.
(*fist<mode>2_ceil_1, fistdi2_ceil, fistdi2_ceil_with_temp)
(fist<mode>2_ceil, fist<mode>2_ceil_with_temp): New isns patterns
