Updated patch for PR19808.

I updated my patch to include a testcase, and I also fixed the case for
anonymous unions.
Things not working right (as far as i know) in this patch yet are:
* references
* pointers
* multiple uninitialized values being used to initialize a single field. (I'm
also not sure how to test for this in the testsuite)
