by adding the new OP_ReleaseReg opcode to tell MemAboutToChange() that a
range of registers is no longer needed so that the source register can be
freely changed. This is a change to debugging and test builds only and
does not impact release builds. Fix for ticket
[c62c5e58524b204d] and [5ad2aa6921faa1ee]. The previous fix to ticket
[5ad2aa6921faa1ee] is backed out by this change since this change is a better
fix.

OP_RealAffinity, to avoid problems with a pointer accounting assert.
This change is not strictly necessary - the correct answer is obtained
without it and no UB occurs - however the pointer accounting asserts are
useful to prevent other problems so it is a simple matter to bring this
piece into compliance. Ticket [5ad2aa6921faa1ee]
