Backport of 8277529: SIGSEGV in C2 CompilerThread Node::rematerialize() compiling Packet::readUnsignedTrint
New implementation taken from 17u backport https://github.com/openjdk/jdk17u/commit/aa11a935373686bf5d67afb89368931c995824f6
That fits into 11u with one trivial manual integration of initialization `_data_dependency_on(NULL)`.
