i386: Always enable mov<V_32:mode> patterns [PR103894]
Middle end tries to generate V4QImode moves to implement V2QImode inserts
and calls emit_move_multi_word when V4QImode moves are unavailable, as is
the case with 32-bit vector moves, constrainted with TARGET_SSE2.
However, this triggers
gcc_assert (mode_size >= UNITS_PER_WORD);
in emit_move_multi_word, since mode_size of V4QImode operand is less than
UNITS_PER_WORD of 64-bit targets.
The patch unconditionally enables 32-bit vector moves to match 16-bit
vector moves. This also enables implementation of 32-bit vector logic
operations with GPR in a follow-up patch.
