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

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.

267a9448ea ppctest: Fix floating-point tests. 
genppctests.py
- Fix incorrect bits for some floating-point instruction opcodes or fields.
- Use separate register for FP results like DolphinPPCTests does.
- Remove extra FMULS.
- Use a regular expression for parsing ppcfloattest.txt. Don't parse the values, just put them in the output ppcloattests.csv file.

ppcfloattest.txt
- Clear crf0 and crf7 because we only care about crf1.
- Use values from DolphinPPCTests (0.0, 0.5, 1.0, 3.5, DBL_MAX, FLT_MAX, 2.4679999352, 4.9359998704, etc.). Some of the values were rounded. This will un-round them. Specify snan or qnan instead of nan.
- One of the FCMPO and FCMPU tests had qnan instead of snan input values.

ppcfloattest.csv
- Regenerate this file using the updated genppctests.py which uses the updated ppcfloattest.txt.

ppctests
- Update double_from_string to be able to parse the new values (snan, qnan, FLT_MAX, DBL_MAX).
