intercept-rethrow-exception.cc fails when running runtimes tests if linking in a hermetic libc++abi. This is because if libc++abi is used, then asan expects to intercept __cxa_rethrow_primary_exception on linux, which should unpoison the stack. If we statically link in libc++abi though, it will contain a strong definition for __cxa_rethrow_primary_exception which wins over the weakly defined interceptor provided by asan, causing the test to fail by not unpoisoning the stack on the exception being thrown. It's likely no one has encountered this before and possible that upstream tests opt for dynamically linking where the interceptor can work properly. An ideal long term solution would be to update the interceptor and libc++[abi] APIs to work for this case, but that will likely take a long time to work out. In the meantime, since the test isn't necessarily broken, we can just add another REQUIRES check to make sure that it's only run if we aren't statically linking in libc++abi.
