* genopinit.c (optabs): Change lfloor_optab and lceil_optab
to conversion optabs.
* optabs.c (init_optabs): Initialize lfloor_optab and lceil_optab
as conversion optab.
* optabs.h (enum optab_index): Remove OTI_lfloor and OTI_lceil.
(enum convert_optab_index): Add COI_lfloor and COI_lceil.
(lfloor_optab, lceil_optab): Adjust defines.
* builtins.c (expand_builtin_int_roundingfn): Adjust for
lfloor and lceil optabs now being conversion optabs.
* config/i386/i386-protos.h (ix86_expand_lfloorceil): Declare.
* config/i386/i386.c (ix86_expand_sse_compare_and_jump):
New static helper function.
(ix86_expand_lfloorceil): New function to expand lfloor and
lceil inline.
* config/i386/i386.md (lfloor<mode>2): Split into ...
(lfloorxf<mode>2): ... x87 variant
(lfloor<mode>di2, lfloor<mode>si2): ... and SSE variants
using ix86_expand_lfloorceil.
(lceil<mode>2, lceilxf<mode>2, lceil<mode>di2, lceil<mode>si2):
Likewise.
* doc/md.texi (lfloorMN, lceilMN): Document.
