...
Emit warning about TraceDependencies results in
ClassHierarchyWalker::count_find_witness_calls() only if TraceDependencies is
actually enabled. Use standard warning() function instead of ad hoc printing.
Remove warning about using Stress(LCM|GCM|IGVN) without LogCompilation in
Compile::Compile(), and add the information to the description of the StressSeed
option instead. These changes prevent false test failures when using
LogCompilation or Stress(LCM|GCM|IGVN).

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.
