mn10300: Use the STC bb-reorder algorithm at -Os
For mn10300, STC still gives better results for optimise-for-size than
"simple" does. So use STC at -Os as well.

* common/config/mn10300/mn10300-common.c
(mn10300_option_optimization_table) <OPT_freorder_blocks_algorithm_>:
Use REORDER_BLOCKS_ALGORITHM_STC at -Os and up.
