SLP: Have vectorizable_slp_permutation set type on invariants
This modifies vectorizable_slp_permutation to update the type of the children
of a perm node before trying to permute them. This allows us to be able to
permute invariant nodes.
This will be covered by test from the SLP pattern matcher.
gcc/ChangeLog:
* tree-vect-slp.c (vectorizable_slp_permutation): Update types on nodes
when needed.
