e7d8e71297 ppc: make ppc_effective_address into a local
There's no reason for it to be a global, we always set it and use it
in instruction implementations, and we never read it directly.

Perhaps the compiler could optimize this away, but it's better to be
simpler (and also be easier to read).

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.
