4e8338eb13 8255763: C2: OSR miscompilation caused by invalid memory instruction placement 
Disable GCM hoisting of memory-writing nodes for irreducible CFGs. This prevents
GCM from wrongly "hoisting" stores into descendants of their original loop. Such
an "inverted hoisting" can happen due to CFGLoop::compute_freq()'s inaccurate
estimation of frequencies for irreducible CFGs.

Extend CFG verification code by checking that memory-writing nodes are placed in
either their original loop or an ancestor.

Add tests for the reducible and irreducible cases. The former was already
handled correctly before the change (the frequency estimation model prevents
"inverted hoisting" for reducible CFGs), and is just added for coverage.

This change addresses the specific miscompilation issue in a conservative way,
for simplicity and safety. Future work includes investigating if only the
illegal blocks can be discarded as candidates for GCM hoisting, and refining
frequency estimation for irreducible CFGs.

Check for nodes missed by remove_useless_nodes() only if PhaseRemoveUseless has

crashing trivially, although implicit assumptions in other parts of C2 about the
existence of loop safepoints might lead to more subtle failures for more complex
methods.
