target/mips: use lookup_and_goto_ptr on BS_STOP
The TB after BS_STOP is not fixed (e.g. helper_mtc0_hwrena changes hflags, which ends up changing the TB flags via cpu_get_tb_cpu_state). This requires a full lookup (i.e. with flags) via lookup_and_goto_ptr instead of gen_goto_tb, since the latter only looks at the PC for in-page goto's. Fix it.
