This patch fixes PR13624, which notes a 64-bit PowerPC ELF ABI
incompatibility with how complex values are returned. It is sufficient
to flag all complex types as direct rather than indirect.
A new test case is provided that checks correct IR generation for the
various supported flavors of _Complex.
