59bee01c0a ppcfpopcodes: Fix fmsubs inf nan check. 
There's probably still an issue with the inf_nan check
using reg_a for the first value instead of reg_a * reg_c.
This will probably need rewriting anyway.

fd81d7b040 ppcfpopcodes: Fix load float. 
Type casting an int to a float assigns the value of the int to the float which is not what is needed here.
