Cleanup: Platform CPU enum, MachineDescription,
Platform: - enum CPUFamily is part of CPUType - DALVIK -> ANDROID - ARM: ARM + ARMv[567] MachineDescription - self contained - static size/alignment Config (enum) for unix32, unix64, win32, win64 and armeabi - add 'long double' - Removed MachineDescription32Bit, MachineDescription64Bit - createStatic(..) uses OS/CPU to fetch best match if not at runtime FIXES: JavaEmitter's struct-emit: Proper 32/64 struct sizes TODO: StructAccessor's mapping to <Type>Buffer w/ index os sizeof(<Type>) doesn't work, since offset may not be multiple of sizeof(<Type>)! i.e. typedef struct { int8_t bits1; // +1 - 0 // +3 (p32) int32_t id; // +4 - 4 int8_t bits2; // +1 - 8 // +3 (p32) - int64_t long0; // +8 - 12 so "longBuffer.get(<type-sized index>)" is invalid, but "byteBuffer.getLong(<byte index>)" must be done. The actual impl. doesn't matter, hence dropping the other nio type mappings is good.
