if the offset fits in 11 bits. This makes use of the fact that the abi

bits. It will be shifted left and sign extended before being actually used.

This is complicated by backward labels (e.g., 0b can be both a backward label
and a binary zero). The current implementation assumes [0-9]b is always a
label and thus it's possible for 0b and 1b to not be interpreted correctly for
ms-style inline assembly. However, this is relatively simple to fix in the
inline assembly (i.e., drop the [bB]).
This patch also limits backward labels to [0-9]b, so that only 0b and 1b are
