i386: Add ssse3_pmulhrswv4hi3 expander

Browse Source 
There is no V4HI pmulhrsw in AVX512BW and V4HI/V8HI pmulhrsw don't require
AVX2.

	PR target/89372
	* config/i386/sse.md (ssedoublemode): Remove V4HI.
	(PMULHRSW): Likewise.
	(<ssse3_avx2>_pmulhrsw<mode>3): Require TARGET_SSSE3, not
	TARGET_AVX2.
	(ssse3_pmulhrswv4hi3): New expander.
