Use uint16_t, as the field is not signed.

After read through target-arm/translate-a64.c, I guess, the main reason
is: the zero register (r31) shares with the sp register (also r31).
- So it uses cpu_reg() and cpu_reg_sp() for them.

Be careful of skipping instructions in general, since for example a ld

For me, if the raw integer is only used once, we needn't define a macro

The advantage of names even in this case is that you can group all the

I replied elsewhere about the zero register.
OK, thanks.

Similarly, if any pipeline takes an exception (a TLB fault from a memory op,
a GPV fault from an illegal mfspr, etc) then no pipeline completes its
