All ~82 MIPSInt::Int_* functions (Interpreter.cpp/.h,
InterpreterVFPU.cpp/.h) now take an explicit MIPSState *mips instead
of reaching for the global currentMIPS internally, along with their
file-local helpers (DelayBranchTo, SkipLikely, ApplySwizzleS/T,
ApplyPrefixD/ST, RetainInvalidSwizzleST, EatPrefixes). MIPSInterpretFunc,
Interpret(), ExecInstruction()/InterpreterDispatch.cpp (regenerated),
and RunUntilFast() all thread mips through accordingly.
Deliberately left on currentMIPS for now: MIPSVFPUUtils.cpp's
ReadVector/WriteVector/ReadMatrix/WriteMatrix/VFPURewritePrefix -
these are shared with every JIT backend's compile-time VFPU code, so
parameterizing them would balloon this into a JIT-wide refactor. This
is a partial refactor; that's the next boundary to push on.
Several JIT backends (x86 Jit.cpp, ARM/ArmJit.cpp, ARM64/Arm64Jit.cpp,
x86/X64IRJit.cpp, RiscV/RiscVJit.cpp, LoongArch64/LoongArch64Jit.cpp,
ARM64/Arm64IRJit.cpp) bake the raw interpreter function pointer
directly into JIT-generated machine code as their "fall back to the
interpreter for this one op" mechanism, with only a single argument
register set up for the call. Rather than hand-editing register
allocation across four architectures that can't be build-tested here,
added MIPSInterpretTrampoline(MIPSOpcode op) - a 1-arg wrapper around
MIPSInterpret(currentMIPS, op) - and pointed all 7 such call sites at
it instead, leaving that codegen untouched. Two other call sites
(JitLogMiss, JitBranchLog) were plain C++ calls and just got the
extra argument directly.
Verified (Windows x64): PPSSPPWindows/PPSSPPHeadless/UnitTest all
build clean, 49/49 unit tests pass. `test.py -g --graphics=software`:
interpreter 312/314 (cpu/fpu/fpu is the pre-existing, unrelated
interpreter-vs-JIT denormal difference; gpu/rendertarget/copy passes
standalone, so was cross-test state bleed in the batch run, not a
regression), default JIT 314/314, jit-ir 313/314 (gpu/vertices/morph
is an expected difference from the vertex decoder taking a different
mode with this core change, not a bug).

* Rename LogType to Log
* Explicitly use the Log:: enum when logging. Allows for autocomplete when editing.
* Mac/ARM64 buildfix
* Do the same with the hle result log macros
* Rename the log names to mixed case while at it.
* iOS buildfix
* Qt buildfix attempt, ARM32 buildfix
Instead of relying on manually passed down flags from CMake,
we now have ppsspp_config.h file to create the platform defines for us.
This improves support for multiplatform builds (such as iOS).
This handles both loops (first step is known) and static branches (some
code uses them instead of jumps, and we disassemble that to "b".)
Not likely to be a big improvement, but might help if the branch predictor
was wrong.
This is as opposed to continuing, which would build a larger jit block.
