ARM: keep a handle to the PC
Keep a handle to the PC in "struct arm", and use it. This register is used a fair amount, so this is a net minor code shrink (other than some line length fixes), but mostly it's to make things more readable. For XScale, fix a dodgy sequence while stepping. It was initializing a variable to a non-NULL value, then updating it to handle the step-over-active-breakpoint case, and then later testing for non-NULL to see if it should reverse that step-over-active logic. It should have done like ARM7/ARM9 does: init to NULL. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
