i386: Add variable vec_set for 32bit vectors [PR97194]
To generate sane code a SSE4.1 variable PBLENDV instruction is needed.
Also enable variable vec_set through vec_setm_operand predicate
for TARGET_SSE4_1 instead of TARGET_AVX2. ix86_expand_vector_init_duplicate
is able to emulate vpbroadcast{b,w} with pxor/pshufb.

* config/i386/predicates.md (vec_setm_operand): Enable
register_operand for TARGET_SSE4_1.
* config/i386/mmx.md (vec_setv2hi): Use vec_setm_operand
as operand 2 predicate. Call ix86_expand_vector_set_var
for non-constant index operand.
(vec_setv4qi): Use vec_setm_mmx_operand as operand 2 predicate.
