[jdk17u-dev] RFR: 8292301: [REDO v2] C2 crash when allocating array of size too large

[Goetz Lindenmaier]

I had to resolve three files:
src/hotspot/share/opto/callnode.cpp
AllocateArrayNode::Ideal could not be deleted automatically.
The patch removes       igvn->add_input_to(phase->C->root(), halt);
but 11 has              phase->C->root()->add_req(halt);
Just deleted anyways.

src/hotspot/share/opto/loopopts.cpp
In the source, clone_loop() has been refactored.
The patch touches code moved to finish_clone_loop().
The very same code is in clone_loop() in 17. Moved
hunk there.

src/hotspot/share/opto/phaseX.cpp
Just placement of a comment.
