PR tree-optimization/55124
* tree-ssa-pre.c (find_or_generate_expression): Instead of
ICEing when we are not able to generate an expression defer it
by signalling failure. Fix possible wrong-code issue by
not picking random REFERENCE expressions as fallback.
(create_component_ref_by_pieces_1): Adjust. Add failure paths.
(create_expression_by_pieces): Likewise.
(insert_into_preds_of_block): When expression generation failed
for one edge make sure to not insert a PHI node.
* gcc.dg/torture/pr55124.c: New testcase.
