Build on Jordan's patch to allow direct branching and USE_REG_TB
to co-exist. Use the power9 addpcis wherever pc-relative addrs
might be handy. Merge in my power10 patches for prefixed insns.
Finish up with an RFC to disable TCG_REG_TB for power9+, when
pc-relative code sequences exist. I've only lightly tested this,
and it seems to increase code size by a few insns per TB. It
really depends on how much we end up using the constant pool.
What is needed is to determine if !TCG_REG_TB helps. If it doesn't,
then some of these patches could be dropped as unreachable.
