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

7f229b0fe8 ppcfpopcodes: Fix fcmpo/fcmpu.
It was always changing CR1 (starting at CR bit 4) instead of the CR selected by crfD.
Also, it was clearing all but the FL,FG,FE,FU bits of FPRF of FPSCR.

e9bc8926ab Avoid some undefined behavior
The `SubOpcode31Grabber[1024] = { ppc_illegalop }` initializer only
populates the first entry with ppc_illegalop (at least on some compilers),
switch to explicitly initializing the entire array with std::fill_n.

Also fix a couple of sign and overflow issues flagged by the Xcode
undefined behavior sanitizer.
