Soft-float arithmetic and comparisons, float/double/x87 conversions to and from
32-, 64- and 128-bit integers, __extendsfdf2, __truncdfsf2, complex
multiplication and division and __powixf2, matching the libc.prx bundled with
PPSA08427: soft-float results ignore MXCSR and raise no flags, division flushes
subnormal quotients, NaN payloads are moved unshifted and float-to-integer
conversions do not saturate.
