accel/tcg: Handle get_page_addr_code() returning -1 in tb_check_watchpoint()
When we support execution from non-RAM MMIO regions, get_page_addr_code() will return -1 to indicate that there is no RAM at the requested address. Handle this in tb_check_watchpoint() -- if the exception happened for a PC which doesn't correspond to RAM then there is no need to invalidate any TBs, because the one-instruction TB will not have been cached.
