Instead, with this fix, we will deoptimize and let the interpreter handle it.  This aligns compiled execution with interpreted.  The new test checks this with a somewhat odd construction: an exception handler that is considered not because it is a match, but because the type in the catch is inaccessible.  In this case the interpreter rethrows IllegalAccessError, not from the bci of the instruction that caused the original exception, but from the bci of the non-matching exception handler.  Whether or not this is the correct behavior for the interpreter is a separate issue.  For now the compiler will continue to follow the precedent set by the interpreter.

This pull request has now been integrated.
