Objective-C, Darwin: Fix a regression in handling bad receivers.
This is seen on 32b hosts with a 64b multilib, and is an ICE when
the build has checking enabled. The fix is to exit the routine
early if the sender or receiver are already error_mark_node.
gcc/objc/ChangeLog:
* objc-next-runtime-abi-02.cc
(build_v2_objc_method_fixup_call): Early exit for cases
where the sender or receiver are known to be in error.
