Proof-of-concept patch v2

In case anyone wants to apply it locally, here's an updated version that also
catches log2(0.0) and inversesqrt(0.0), and also works for vector operands. 
With this version, I haven't seen any glitches in >10h of FF14 gameplay. 
Interestingly, I didn't see any significant difference in benchmark performance
from 3-run averages with and without the patch (in fact, the average score was
slightly better with the patch applied, though I suspect that's just random
variation).
