i386: Remove mode size check in ix86_get_ssemov

Even though ix86_hard_regno_mode_ok doesn't allow xmm16-xmm31 nor
ymm16-ymm31 in 128/256 bit modes when AVX512VL is disabled, LRA can
still generate reg to reg moves with xmm16-xmm31 and ymm16-ymm31 in
128/256 bit modes.  Remove mode size check in ix86_get_ssemov.
