MechaCat02 6fe2cbf251 fix(cpu): PPCBUG-426/427/433 single-FMA vnmsubfp + vctsxs NaN saturation

Phase 5 batch 6 (5f): saturation and FMA-rounding fixes.

- PPCBUG-426 vnmsubfp: was `bi - ai * ci` (two rounding steps); now
  `-ai.mul_add(ci, -bi)` which is mathematically equivalent (= bi - ai*ci)
  but uses a single FMA round per ISA.
- PPCBUG-427 vnmsubfp128: same single-FMA fix.
- PPCBUG-433 vctsxs / vcfpsxws128 NaN saturation: AltiVec ISA saturates
  NaN to INT_MIN (0x80000000); xenia returned 0. The vctuxs (unsigned)
  NaN→0 is correct per ISA.
