This patch solves a problem with passing varargs parameters under the PPC64
ELF ABI.
A varargs parameter consisting of a single-precision floating-point value,
or of a single-element aggregate containing a single-precision floating-point
value, must be passed in the low-order (rightmost) four bytes of the
doubleword stack slot reserved for that parameter. If there are GPR protocol
registers remaining, the parameter must also be mirrored in the low-order
four bytes of the reserved GPR.
Prior to this patch, such parameters were being passed in the high-order
four bytes of the stack slot and the mirrored GPR.
The patch adds a new test case to verify the correct code generation.
