target-ppc: fix SPE comparison functions
efstst*() functions are fast SPE funtions which do not take into account
special values (infinites, NaN, etc.), while efscmp*() functions are
IEEE754 compliant.
Given that float32_*() functions are IEEE754 compliant, the efscmp*()
functions are correctly implemented, while efstst*() are not. This
patch reverse the implementation of this two groups of functions and
fix the comments. It also use float32_eq() instead of float32_eq_quiet()
as qNaNs should not be ignored.
