Make code compile, function and actually follow the EABI

Also fix alignment issues in the EABI portion itself. In ARM64, SP is always kept with 16 byte alignment. Examples with -72 offsets or the compact format itself spec, which mentioned 4088 were trivially incorrect. Fix syntax errors, negative/positive errors, register names errors as well. All provided canonical code now compiles, functions and follows the EABI.
