Summary

Experimenting with aligning with GCC LIR behavior at Os

Note:
GCC only transforms loop into memset, memcpy and movmove if
-ftree-loop-distribute-patterns or -ftree-loop-distribution are given.
And it does not transform at -Os even when these options are given.
Both options are enabled at -O3.
