[LLVMdev] Proposed patches for Clang 3.5.1

[Dimitry Andric]

I still have the preprocessed, minimized version of the FreeBSD stage 2 boot loader lying around.  This is IMHO quite a nice testcase, but it needs some test framework logic to be able to count section sizes, etc.  Can we assume size(1) is usable, or does the test framework already something for this?
