Finish handler

[fjtrujy]

Create specific functions to make it easier to deal with the finish handler interruption.
Additionally I have enabled also LTO

What happens to:

gsKit/ee/gs/src/gsCore.c

Lines 124 to 127 in 2897eec

	void gsKit_finish(void)
	{
	while(!(GS_CSR_FINISH));
	}

After registering a finish handler? Can they be used at the same time?

Yes, actually it is still being used
