This avoids a DCHECK failure if we continue using the Assembler after
code generation abortion. Even though it might not be the best style to
still call methods on the Assembler after abortion, it's not a problem
apart from the firing DCHECK, so we apply this simple fix instead of
making sure to really abort everything immediately.
