Pass outptr as in rustboot. Probably need to revisit this ABI. Also disgusting hack employed. Please remove.

Store items and decls in vecs to preserve input order, index externally. Implement block-local name lookup.

Encode and decode tag types in dwarf properly. Add list module to std. Shift rustc to use std.util.option. Fix various dependent bugs. Closes #73.

Patchwork of attempted fixes to effect system and gc system; eventually give up and disable it entirely in the runtime. Will need extensive reworking.

First linkable and executable translation from rustc. Upcalls to log, passes wrong arg, crashes. Baby steps.

Translate a bunch of the material (lltrans, llasm, abi) from rustboot to rustc, and move files around.
