Make use of lock bits in reservation counters.
On PPU, fallback to compare_and_swap instead of desperate retry.
On SPU, lighten write set on retry by 'locking' outside of the transaction.
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)
Are made composable in expressions similar to arithmetic ops.
Implement noncast in addition to bitcast (no-op case).
Implement bitcast constant folding.
Fixed some misuse of sext<>.
* Fix SPU LR event setting in atomic commands according to hw test
* MFC: increment timestamp for PUT cmd in non-tsx path
* MFC: fix reservation lost test on non-tsx path in regard to the lock bit
* Reservation notification moved out of writer_lock scope to reduce its lifetime
* Use passive_lock/unlock in ppu atomic inctrustions to reduce redundancy
* Lock only once for dma transfers (non-TSX)
* Don't use RDTSC in reservation update logic
* Remove MFC cmd args passing to process_mfc_cmd
* Reorder check_state cpu_flag::memory check for faster unlocking
* Specialization for 128-byte data copy in SPU dma transfers
* Implement memory range locks and isolate PPU and SPU passive lock logic
Implement helper functions balanced_wait_until and balanced_awaken
They include new path for Windows 8.1+ (WaitOnAddress)
shared_mutex, cond_variable, cond_one, cond_x16 modified to use it
Added helper function utils::popcnt16
Replace most semaphore<> with shared_mutex
Remove "atomic operator" classes
Remove test, test_and_set, test_and_reset, test_and_complement global functions
Simplify atomic_t<> with constexpr if, remove some garbage
Redesign bs_t<> to use class, mark its methods constexpr
Implement atomic_bs_t<> for optimizations
Remove unused __bitwise_ops concept (should be in other header anyway)
Bitsets can now be tested via safe bool conversion
Build SPU cache after PPU, fix mixing progress
SPU ASMJIT: add support for Giga mode
SPU ASMJIT: use the same spu.log location as SPU LLVM
SPU: improve spu.log disasm
SPU: improve trampolines, unify with SPU ASMJIT
SPU: decode interrupt handler address from BR/BRA at 0x0
SPU LLVM: support Mega/Giga modes
SPU LLVM: implement function chunks
SPU LLVM: use PHI nodes, value visibility across basic blocks
SPU LLVM: implement function chunk table
New simple memory manager for LLVM (bugfix)
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
