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)
