Reed Kotler 3589b7b808 Last change for mips16 prolog/epilog cleanup and optimization.
Some tiny cosmetic code changes to follow. Because of the wide
ranging nature of the patch a full 24 test cycle was needed to
check against regression. This was the smallest patch I could
make to progress from the earlier ones in the series.
