2e90bd94de Continued sketching out code for checking states against preconditions.
It's still sketchy. I added a typestate annotation field to statements
tagged stmt_decl or stmt_expr, because a stmt_decl statement has a typestate
that's different from that of its child node. This necessitated trivial
changes to a bunch of other files all over to the compiler. I also added a
few small standard library functions, some of which I didn't actually end
up using but which I thought might be useful anyway.

b8bb2e118e Further on the path toward self-awareness.
Mostly:

  * Merciless refactoring of trans.rs so that trans_call can work for
    self-calls as well as other kinds of calls

Also:

  * Various changes to go with having idents, rather than exprs, in
    expr_call_self AST nodes
  * Added missing case for SELF token to token.to_str()

3130348ee1 Started adding support for typestate checking.
I added a new field to the ast "ann" type for typestate information.
Currently, the field contains a record of a precondition bit vector and
postcondition vector, but I tried to structure things so as to make
it easy to change the representation of the typestate annotation type.
I also had to add annotations to some syntactic forms that didn't have
them before (fail, ret, be...), with all the boilerplate changes
that that would imply.

The main call to the typestate_check entry point is commented out and
the actual pre-postcondition algorithm only has a few cases
implemented, though the overall AST traversal is there. The rest of
the typestate algorithm isn't implemented yet.
