tcg: Add TranslationBlock.jmp_insn_offset
Stop overloading jmp_target_arg for both offset and address,
depending on TCG_TARGET_HAS_direct_jump. Instead, add a new
field to hold the jump insn offset and always set the target
address in jmp_target_addr[]. This will allow a tcg backend
to use either direct or indirect depending on displacement.
