The earlier the vector lowering is moved in the pass list, the higher
are the possibilities that match.pd or some other optimization reintroduces

The following amends the PR114070 fix to optimistically allow
the folding when we cannot expand the current vec_cond using
vcond_mask and we're still before vector lowering. This leaves
a small window between vectorization and lowering where we could
break vec_conds that can be expanded via vcond{
