tree-optimization/110742 - fix latent issue with permuting existing vectors
When we materialize a layout we push edge permutes to constant/external
defs without checking we can actually do so. For externals defined
by vector stmts rather than scalar components we can't.
PR tree-optimization/110742
* tree-vect-slp.cc (vect_optimize_slp_pass::get_result_with_layout):
Do not materialize an edge permutation in an external node with
vector defs.
(vect_slp_analyze_node_operations_1): Guard purely internal
nodes better.
* g++.dg/torture/pr110742.C: New testcase.
