vect: Consider vec_perm costing for VMAT_CONTIGUOUS_REVERSE
For VMAT_CONTIGUOUS_REVERSE, the transform code in function
vectorizable_store generates a VEC_PERM_EXPR stmt before
storing, but it's never considered in costing.
This patch is to make it consider vec_perm in costing, it
adjusts the order of transform code a bit to make it easy
to early return for costing_p.
gcc/ChangeLog:
* tree-vect-stmts.cc (vectorizable_store): Consider generated
VEC_PERM_EXPR stmt for VMAT_CONTIGUOUS_REVERSE in costing as
vec_perm.
gcc/testsuite/ChangeLog:
* gcc.dg/vect/costmodel/ppc/costmodel-vect-store-2.c: New test.
