Add a new 'eRegisterInLiveRegisterContext' RegisterLocation to track
a register value that is live in the stack frame 0 register context.
Fixes a problem where retrieving a register value on stack frame #n
would involved O(n!) stack frame checks. This could be very slow on
a deep stack when retrieving register values that had not been
modified/saved by any of the stack frames. Not common, but annoying
when it was hit.
