PR target/24879
* config/i386/i386.c (ix86_init_mmx_sse_builtins): Add
void_ftype_di_di and void_ftype_pcvoid_di_di. Use void_ftype_di_di
on __builtin_ia32_mwait and void_ftype_pcvoid_di_di on
__builtin_ia32_monitor for 64bit.
(ix86_expand_builtin): Support 64bit monitor and mwait.
* config/i386/pmmintrin.h (_mm_monitor): Remove macro. Use
inline function.
(_mm_mwait): Likewise.
* config/i386/sse.md (sse3_mwait): Make it 32bit only.
(sse3_mwait64): New. 64bit mwait.
(sse3_monitor): Make it 32bit only.
(sse3_monitor64): New. 64bit monitor.
