Emulate MMX plusminus/sat_plusminus with SSE. Only SSE register source
operand is allowed.
PR target/89021
* config/i386/mmx.md (<plusminus_insn><mode>3): New.
(*mmx_<plusminus_insn><mode>3): Changed to define_insn_and_split
to support SSE emulation.
(*mmx_<plusminus_insn><mode>3): Likewise.
(mmx_<plusminus_insn><mode>3): Check TARGET_MMX_INSNS instead of
TARGET_MMX.
