[PATCH] Adjust testcases to be robust against operand order changes

[Richard Biener]

When folding all stmts we can end up canonicalizing operand order
correctly which breaks at least the following two testcases.

Fixed by making their expected outcome more robust.

Tested on x86_64-unknown-linux-gnu, applied.

Richard.

        * gcc.dg/tree-ssa/slsr-19.c: Make robust against operand order changes.
        * gcc.dg/tree-ssa/reassoc-20.c: Likewise.
