[PATCH 40/42] i386: Allow MMX intrinsic emulation with SSE

Allow MMX intrinsic emulation with SSE/SSE2/SSSE3. Don't enable MMX ISA by default with TARGET_MMX_WITH_SSE. For pr82483-1.c and pr82483-2.c, "-mssse3 -mno-mmx" compiles in 64-bit mode since MMX intrinsics can be emulated wit SSE. gcc/ PR target/89021 * config/i386/i386-builtin.
