[cfe-commits] Fix handling of ARM homogenous aggregates

[Anton Korobeynikov]

Hi Bob et al

Attached patch addresses the following issues:

> * More seriously, I don't see how you can get away with asserting on unions in CodeGenFunction::ExpandTypeFromArgs.  Am I missing something?
> * I don't much like the code duplication for the "expand a field" code in ExpandTypeToArgs.  If you can get away with just grabbing the first field of a union, I think you could unify that into a single loop over the fields and just exit after the first iteration in the case of a union.  Otherwise, maybe you could factor that code out into a separate function.

I do not attach the testcases once again here just to simplify the patch :)
