gcc11-pr94440.patch

I think best would be to get away with the TREE_OPTIMIZATION_NODE vs.
TARGET_OPTIMIZATION_NODE dichotomy and just use one node for both, but that
won't fly in stage3, so this patch essentially forces new target optimizati=
on
nodes to cover even the flag_excess_precision and flag_unsafe_math_optimiza=
tion
stuff, so that the enabled attr etc. can use those.=
