64df253053 ppcexec: Rename bool function enums. 
Use "logical" since the functions deal with multiple bits instead of a single boolean value and because the 601 manual calls them Logical Instructions.
Use "ppc" for the enums because logical_and is defined elsewhere and because the original DPPC code used these names for those functions.

67bd47f11f ppcopcodes: Fixes for bcctr(l)?. 
Add MPC601 variants. Variants that decrement and test the ctr are invalid bon't don't appear to trigger an exception. The manual says MPC601 can decrement the counter. Other CPUs do not decrement the counter but will branch based on the value.

fe05b1de12 Fix compiler warnings. 
Xcode build has compiler warnings involving loss of precision. Remove them by adding type casts. Check results in some cases for overflow.

- Remove invalid form check unless you know for sure it's supposed to cause an exception.
- Add register skip for 601 CPU. This needs testing.

d0b0b8070c ppcopcodes: Fix l*ux? invalid form check. 
Invalid form is (reg_a == reg_d) || reg_a == 0.
Therefore, valid form is (reg_a != reg_d) && reg_a != 0
!(a || b) == !a && !b
