i386: Emulate MMX ashr<mode>3/<shift_insn><mode>3 with SSE

Emulate MMX ashr<mode>3/<shift_insn><mode>3 with SSE.  Only SSE register
source operand is allowed.

PR target/89021
* config/i386/mmx.md (mmx_ashr<mode>3): Also allow
TARGET_MMX_WITH_SSE.  Add SSE emulation.
(mmx_<shift_insn><mode>3): Likewise.
(ashr<mode>3): New.
(<shift_insn><mode>3): Likewise.
