fix scalar BB vectorization costing

We were costing the scalar pattern stmts rather than the scalar
original stmt and also not appropriately looking at the pattern
stmt for whether the stmt is vectorized.

2020-07-03  Richard Biener  <rguenther@suse.de>

* tree-vect-slp.c (vect_bb_slp_scalar_cost): Cost the
original non-pattern stmts, look at the pattern stmt
vectorization status.

* gcc.dg/vect/costmodel/x86_64/costmodel-vect-slp-2.c: New
testcase.
