tree-optimization/97806 - fix PRE expression post order
This fixes the postorder compute for the case of multiple
expression leaders for a value.

PR tree-optimization/97806
* tree-ssa-pre.c (pre_expr_DFS): New overload for visiting
values, visiting all leaders for a value. Use a bitmap
for visited values.
(sorted_array_from_bitmap_set): Walk over values and adjust.
* gcc.dg/pr97806.c: New testcase.
