[Qemu-devel] [PATCH] tcg: Improve tcg_out_label and fix its usage for w64 |

tcg_out_label is always called with a third argument of pointer type
which was casted to tcg_target_long.
These casts can be avoided by changing the prototype of tcg_out_label.
There was also a cast to long. For most hosts with
sizeof(long) == sizeof(tcg_target_long) == sizeof(void *) this did not
matter, but for w64 it was wrong. This is fixed now.
