i386: Use the STC bb-reorder algorithm at -Os (PR67864)

For x86, STC still gives better results for optimise-for-size than
"simple" does.  So use STC at -Os as well.

PR rtl-optimization/67864
* common/config/i386/i386-common.c (ix86_option_optimization_table)
<OPT_freorder_blocks_algorithm_>: Use REORDER_BLOCKS_ALGORITHM_STC
at -Os and up.
