In strict PPC ABI mode, pass single FP on stack in double FP format
The EABI and the SVR4 ABI state that single-precision FP arguments passed
on stack are passed as a 64-bit word, extended to double-precision.
This commit implements this behavior by using a stack slot of type Tany64.
Not only this ensures that the slot is of size and alignment 8 bytes,
but it also ensures that it is accessed by stfd and lfd instructions,
using single-extended-to-double format.
