Bill Wendling 5e31474b9c Update the tests. 
This update coincides with r174110. That change ordered the attributes
alphabetically.

Rafael Espindola b48280ba17 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.
