Updated webrev:

I ran compiler regression tests with disable dioptimization for 
exceptions processing. And 2 tests failed because thrown exception 
(NegativeArraySizeException) during runtime call was not caught by catch 
block. The problem was C2 expected only OutOfMemoryError (which is not 
Exception) from slow allocation runtime calls. I replaced it with 
Throwable which C2 uses for other calls.
