Slava Zakharin 9c0acc42e8 [flang] Run algebraic simplification optimization pass.
Try 2 to merge 4fbd1d6c872e8228f23a6e13914222af40ca6461.

Flang algebraic simplification pass will run algebraic simplification
rewrite patterns for Math/Complex/etc. dialects. It is enabled
under opt-for-speed optimization levels (i.e. for O1/O2/O3; Os/Oz will not
enable it).

With this change the FIR/MLIR optimization pipeline becomes affected
by the -O* optimization level switches. Until now these switches
only affected the middle-end and back-end.
