Roll gofrontend to a6e10414311a

This takes us to Go 1.4. Also includes a couple of changes to the test
suite, both in the runtime package:

- Disable TestSetPanicOnFault. We cannot support this scenario at all,
  due to LLVM's lack of non-call exceptions.

- Tweak TestFinalizerType. This test only passes with two GC runs.
