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.

Add block_to_str and expr_to_str methods to the pprust module.
...
Since pprust is authed impure these can be used for debug logging.

Started adding support for floating-point type, floating-point literals, and logging of floats. Other operations on float probably don't work yet.
