which can cause problems on shutdown after a LEFT JOIN.

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]

table that is in a LEFT JOIN, be sure to set the correct Expr.iRightJoinTable
value. This value does not appear to ever be used, except inside of a single
assert(). But it is good to set it correctly, nevertheless. This fixes
ticket [7929c1efb2d67e98], which as far as I can tell is completely harmless.

of expressions used in an index-on-expression directly from the index rather
than recomputing the value. If the expression has a top-level COLLATE or
unlikely() operator, be sure to clear the corresponding flags prior to
converting it into a TK_COLUMN expression. Failure to do this is most likely
harmless in production, but might cause an assertion fault in debugging builds.
