Enable REE for H8
I was looking at H8 assembly code recently and noticed we had unnecessary
extensions. As it turns out we never enabled redundant extension elimination
on the H8. This patch fixes that oversight (and was the trigger for the
failure fixed my the prior patch).
gcc/common
* common/config/h8300/h8300-common.cc (h8300_option_optimization_table):
Enable redundant extension elimination at -O2 and above.
