Say for which mode please? Like
(vcond_mask_ for VEC_I and VEC_I): New expand.

"for VEC_I and VEC_F", here, but the actual names in the pattern are for
vector m
Fixed one place without consistent mode.
Bootstrapped and regress testing passed on powerpc64le-linux.
Thanks!

Hi,
To support full condition reduction vectorization, we have to define
vec_cmp_* and vcond_mask_*. This patch is to add related expands.
Add vector_{ungt,unge,unlt,unle} for unique vector_*
interface support.
Regression testing just launched.
