i386: Fix REDUC_SSE_SMINMAX_MODE mode conditions.

V4SI, V8HI and V16QI modes of redux_<code>_scal_<mode> expander
expand with SSE2 instructions (PSRLDQ and PCMPGTx) so use
TARGET_SSE2 as relevant mode iterator codition.

	PR target/94494
	* config/i386/sse.md (REDUC_SSE_SMINMAX_MODE): Use TARGET_SSE2
	condition for V4SI, V8HI and V16QI modes.

testsuite/ChangeLog:

	PR target/94494
	* gcc.target/i386/pr94494.c: New test.
