tree-optimization/96579 - another special-operands fix in reassoc

This makes sure to put special-ops expanded rhs left where
expression rewrite expects it.

* tree-ssa-reassoc.c (linearize_expr_tree): If we expand
rhs via special ops make sure to swap operands.

Probably similar to the fallout I fixed in
2c558d2655cb22f472c83e8296b5cd2a92365cd3 (PR96370) where I already suspected
the real issue is still unfixed.  So I'll take a second look.
