rs6000: sysv: Don't pass SFmode in varargs in FPRs
This makes the float32-basic.c testcase work on sysv (32-bit Linux).
"float" is promoted to "double" for varargs. The ABI also only defines
the use of double precision in varargs. But _Float32 is not promoted.
Since there is no way of passing single-precision float in FPRs we
should pass SFmode in GPRs (or memory) instead. This is similar to
the 64-bit ABI.
