Rafael Espindola 06b2b4a7c9 Handle functions with struct arguments or return types and the regparm 
attribute. It is a variation of the x86_64 ABI:

* A struct returned indirectly uses the first register argument to pass the
  pointer.
* Floats, Doubles and structs containing only one of them are not passed in
  registers.
* Other structs are split into registers if they fit on the remaining ones.
  Otherwise they are passed in memory.
* When a struct doesn't fit it still consumes the registers.

Rafael Espindola 74ec5c03ca Attributes preceding a function declaration are first applied to the return 
type and then propagated to the function. This was failing for destructors,
constructors and constructors templates since they don't have a return type.

Fix that by directly calling processTypeAttrs on the dummy type we use as the
return type in these cases.
