Remove message ART creates for "throw null".

The new version of R8 transforms:
  throw new NullPointerException()

Into:
  throw null

ART used to create a message for the pattern "throw null", which is
something that now breaks ObjectsTest.requireNonNull.

Test: libcore.java.util.ObjectsTest#test_requireNonNull_T
