Drop AVX2 path for now, since it usually operates on small data.
Rely on automatic SSE vectorization on recent compilers.
Side refactoring on JIT.h to workaround weird conflict issue.
Basically, using timestamp counter.
Rewritten vm::reservation_op with the same principle.
Rewritten another transaction helper.
Add two new settings for configuring fallbacks.
Two limits are specified in nanoseconds (first and second).
Fix PUTLLC reload logic (prevent reusing garbage).
Remove MemoryManager3 as unnecessary.
Rewrite MemoryManager1 to use its own 512M reservations.
Disabled unwind info registration on all platforms.
Use 64-bit executable pointers under vm::g_exec_addr area.
Stop relying on deploying PPU LLVM objects in first 2G of address space.
Implement jit_module_manager, protect its data with mutex.
Misc: fix EH frame registration (LLVM, non-Windows).
Misc: constant-folding bitcast (cpu_translator).
Misc: add syntax for LLVM arrays (cpu_translator).
Misc: use function names for proper linkage (SPU LLVM).
Changed function search and verification in Giga mode.
Basic stack frame layout analysis.
Function detection in Giga mode.
Basic use of new information in SPU LLVM.
Fixed jump table compilation in SPU LLVM.
Disable broken optimization in Accurate xfloat mode.
Make compiled SPU modules position-independent in SPU LLVM.
Optimizations include but not limited to:
* Compiling SPU functions as native functions when eligible
* Avoiding register context write-out
* Aligned stack assumption (CWD alike instruction)
Is a memory manager for ASMJIT, replaces asmjit::JitRuntime
Unified memory manager for ASMJIT and LLVM
Unified SPU trampoline generation
Remove previous workarounds
Allow parallel compilation of SPU code, both at startup and runtime
Remove 'SPU Shared Runtime' option (it became obsolete)
Refactor spu_runtime class (now is common for ASMJIT and LLVM)
Implement SPU ubertrampoline generation in raw assembly (LLVM)
Minor improvement of balanced_wait_until<> and balanced_awaken<>
Make JIT MemoryManager2 shared (global)
Fix wrong assertion in cond_variable
Drop _xbegin family intrinsics due to bad codegen
Implemented `notifier` class, replacing vm::notify
Minor optimization: detach transactions from global mutex on TSX path
Minor optimization: don't acquire vm::passive_lock on PPU on TSX path
For now, compile only one block at time
Use tail calls to move between blocks
Fully write PPU context (except CIA)
This fixes many compatibility problems
