rG40cef5a00eb8: [clang] Add a test for CGDebugInfo treatment of blocks

Summary

There doesn't seem to be a direct test of this, and I'm planning to make future changes which will affect it.

I'm not particularly familiar with the blocks extension, so suggestions for better tests are welcome.

I think that this should either hardcode a 64-bit architecture or it shouldn't test for explicit offsets.

Don't hardcode x86_64-specific offsets
