sse.md (vec_extract_hi_<mode>, [...]): Use vextracti128 instead of vextractf128 for...

	* config/i386/sse.md (vec_extract_hi_<mode>,
	vec_extract_hi_v16hi, vec_extract_hi_v32qi): Use
	vextracti128 instead of vextractf128 for -mavx2 and
	integer vectors.  For V4DFmode fix up mode attribute.
	(VEC_EXTRACT_MODE): For TARGET_AVX add 32-byte vectors.
	(vec_set_lo_<mode>, vec_set_hi_<mode>): For VI8F_256 modes use V4DF
	instead of V8SF mode attribute.
	(avx2_extracti128): Change into define_expand.
	* config/i386/i386.c (ix86_expand_vector_extract): Handle
	32-byte vector modes if TARGET_AVX.

	* gcc.target/i386/sse2-extract-1.c: New test.
	* gcc.target/i386/avx-extract-1.c: New test.
