Add new parameter to vec_perm_const hook for specifying operand mode.
The rationale of the patch is to support vec_perm_expr of the form:
lhs = vec_perm_expr<rhs, mask>
where lhs and rhs are vector types with different lengths but have
same element type. For example, lhs is SVE vector and rhs
is corresponding AdvSIMD vector.
It would also allow to express extract even/odd and interleave operations
with a VEC_PERM_EXPR. The interleave currently has the issue that we have
to artificially widen the inputs with "dont-care" elements.
