This is the JVM infrastructure for pushing a stack frame *during* a method handle call, so that some sort of intermediate fixup operation can be done before completing the call.
The requirement is that a recognizable stack frame be pushed during the intermediate fixup operation, so that if there is an exception, or a GC, or some other stack walk, the stack will be parsed properly. Crucially, the pending arguments must be recognized as managed pointers.
This is a preliminary review, because it shows just the new stack frame type, rather than the use cases (which are forthcoming).
