the correct set of constraints.

76f4278029 tcg: Add add/sub with carry opcodes and infrastructure 
Liveness needs to track carry-live state in order to
determine if the (hidden) output of the opcode is used.
Code generation needs to track carry-live state in order
to avoid clobbering cpu flags when loading constants.

So far, output routines and backends are unchanged.

6b8abd244b tcg: Introduce the 'z' constraint for a hardware zero register 
For loongarch, mips, riscv and sparc, a zero register is
available all the time.  For aarch64, register index 31
depends on context: sometimes it is the stack pointer,
and sometimes it is the zero register.

Introduce a new general-purpose constraint which maps 0
to TCG_REG_ZERO, if defined.  This differs from existing
constant constraints in that const_arg[*] is recorded as
false, indicating that the value is in a register.
