094d31f5e4 Make lexer buffer the whole file
This way, it won't have to go through a bunch of calls for each
byte fetched.

9c001af07c Implemented computing prestates and poststates for a few expression forms.
The typestate checker (if it's uncommented) now correctly rejects a
trivial example program that has an uninitialized variable.

53cc673db1 Re-add a read_byte() method to buf_reader objs
This was removed because of the repetition, but doing single-byte
reads in terms of read_bytes (which allocates a vec) is needlessly
slow. This change speeds up parsing by 22%.

(Eventually, we won't be able to escape handling the buffering in the
stdlib itself.)

ac3026412b Revise EBML reader API
New one is less stateful, easier to work with.

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.

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.

Finally implements _str.is_utf8, adds from_chars, from_char, to_chars,
char_at, char_len, (push|pop|shift|unshift)_char. Also, proper
character I/O for streams.

bcf04e253f Revert "Remove usages of case(_) { fail; } since the compiler does this automatically". When we have exhaustiveness checking, "case(_) { fail; }" will be useful to silence warnings.
This reverts commit 92a716d862.

441697ab35 Extend stream functionality
Writer and reader streams now come with methods to write and read
little-endian numbers. Whether that is the right place for such
methods is debatable, but for now, that's where they live.

right now, feel free to suggest a cleaner way to do this.
