target/i386: Misc AVX helper prep
Fixup various vector helpers that either trivially exten to 256 bit, or don't have 256 bit variants. No functional changes to existing helpers Signed-off-by: Paul Brook <paul@nowt.org> Message-Id: <20220424220204.2493824-19-paul@nowt.org> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>master
