03568c0d53 tcg: Convert rotl, rotr to TCGOutOpBinary 
For aarch64, arm, loongarch64, mips, we can drop rotl.
For ppc, s390x we can drop rotr.
Only x86, riscv, tci have both rotl and rotr.

8726c7d799 tcg: Do not require both rotr and rotl from the backend 
Many host architectures do not implement both rotate right
and rotate left and require the compiler to negate the
shift count to rotate the opposite direction.  We have been
requiring the backend to perform this transformation.
Do this during opcode expansion so that the next patch
can drop support where possible in the backend.

a3b37bc6fa tcg/arm: Fix constraints for sub 
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.
