Aurelien Jarno 2f93c23fe7 target-ppc: use the softfloat float32_muladd function
Use the new softfloat float32_muladd() function to implement the vmaddfp
and vnmsubfp instructions. As a bonus we can get rid of the call to the
HANDLE_NAN3 macro, as the NaN handling is directly done at the softfloat
level.

Aurelien Jarno db1babb8db target-ppc: use the softfloat min/max functions
Use the new softfloat float32_min() and float32_max() to implement the
vminfp and vmaxfp instructions. As a bonus we can get rid of the call to
the HANDLE_NAN2 macro, as the NaN handling is directly done at the
softfloat level.

Aurelien Jarno ef9bd1507b target-ppc: simplify NaN propagation for vector functions
Commit e024e881bb provided a pickNaN()
function for PowerPC, implementing the correct NaN propagation rules.
Therefore there is no need to test the operands manually, we can rely
on the softfloat code to do that.
