007f9e5309 Jit_Integer: Handle NOP case for oris as well 
Like ori, this can also be used as a NOP under the same conditions.

42fce74f39 Jit_Integer: Handle NOP case where RA == RS for ori 
ori can be used as a NOP if the two register operands are the same, and
the immediate is zero, not only if the two register operands are r0.

Also removes the check for !inst.Rc, as ori only has one encoding, and
said encoding doesn't even have a record bit in it.

e53fffeb90 PowerPC: Properly unset the overflow bit 
The OV bit is non-sticky. Therefore, after an overflow-enabled
instruction executes, if an overflow does *not* occur, then OV is
cleared. SO is sticky however, so it staying set in this case is
correct.

7a2d98b948 JitAsm: Remove use of the JIT global in Generate() 
With this, JitAsm code doesn't have any reliance on the JIT global
variable. This means the core JIT64 code no longer relies on said
global at all. The Jit64 common code, however, still has some offenders.

Notably, EmuCodeBlock and Jit64AsmCommon are the remaining places in the
common code that make use of the global variable.

e0165a62da JitBase: Remove use of the JIT global in Dispatch() and JitTrampoline()

JIT instance we're dispatching or trampolining with as a parameter.

51cfeb8c7d JitBase: Ensure JitOptions and JitState instances are consistently initialized 
Ensures that upon construction of a JitBase instance, that all
underlying members within the option and state structs are guaranteed
to be initialized.

This prevents potentially using a member uninitialized in some form.

2fa0cb91a1 Interpreter_Integer: Set the overflow flag if the OE bit is set for neg 
Also amends the condition that was being checked. Previously it was
checking if the destination register value was 0x80000000, however it's
actually the source register that should be checked.

a0164e14bc BreakPoints: Avoid direct use of the JIT global 
Trims the direct usages of the global by making the code go through the
JIT interface (where it should have been going in the first place).

This also removes direct JIT header dependencies from the breakpoints as
well. Now, no code uses the JIT global other than JIT code itself, and
the unit tests.

Helper_UpdateCR1() does exactly that, so we use it here to perform this
for us.
