tree-optimization/99912 - schedule DSE before SRA
For the testcase in the PR the main SRA pass is unable to do some
important scalarizations because dead stores of addresses make
the candiate variables disqualified. The following patch adds
another DSE pass before SRA forming a DCE/DSE pair and moves the
DSE pass that is currently closely after SRA up to after the
next DCE pass, forming another DCE/DSE pair now residing after PRE.
