tcg: Remove TCG_TARGET_HAS_GUEST_BASE define
GUEST_BASE support is now supported by all TCG backends, and isnow mandatory. Drop the now-pointless TCG_TARGET_HAS_GUEST_BASEdefine (set by every backend) and the error if it is unset.
tcg: remove obsolete jmp op
The TCG jmp operation doesn't really make sense in the QEMU context, itis unused, it is not implemented by some targets, and it is wronglyimplemented by some others.
This patch simply removes it.
