* Record implicit null checks at the actual invoke time.Calin Juravle2015-01-213-0/+263
ImplicitNullChecks are recorded only for instructions directly (see NB below) preceeded by NullChecks in the graph. This way we avoid recording redundant safepoints and minimize the code size increase. NB: ParallalelMoves might be inserted by the register allocator between the NullChecks and their uses. These modify the environment and the correct action would be to reverse their modification. This will be addressed in a follow-up CL. Change-Id: Ie50006e5a4bd22932dcf11348f5a655d253cd898
