For TCI, we're losing type information in the interpreter.
Introduce a tci-specific opcode to handle the difference.

Rename to INDEX_op_divs2 to emphasize signed inputs,
and mirroring INDEX_op_divu2_*. Document the opcode.

Create a special subclass for sub, because two backends can
support "subtract from immediate". Drop all backend support
for an immediate as the second operand, as we transform sub
to add during optimize.

In 7536b82d28 we lost the rI constraint that allowed the use of
RSB to perform reg = imm - reg. At the same time, drop support
for reg = reg - imm, which is now transformed generically to
addition, and need not be handled by the backend.

The instruction set does not implement nor with immediate.
There is no reason to pretend that we do.

Drop all backend support for an immediate as the first operand.
This should never happen in any case, as we swap commutative
operands to place immediates as the second operand.
