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.
