  Fix X86_64 complex-returns for regcall.

D35259 introduced a case where complex types of non-long-double would
result in FI.getReturnInfo() to not be initialized properly.  This
resulted in a crash under some very specific circumstances when
dereferencing the LLVMContext.

This patch makes sure that these types have the intended getReturnInfo
initialization.
