1bec738c56 Support #fmt precision for bools, with same rules as strings
Not totally confident this is desirable. The alternative would be to make it a
compile error.

99a697b56a Add support for upper-case hex and binary output to #fmt.
Only works for uints at present. Necessitated the addition of _str.to_upper.

7c6e6fc5d4 Make expr_while work in typestate_check
Also did some refactoring in typestate_check. All test cases in
compile-fail that involve uninitialized vars now fail correctly!
(All eight of them, that is.)

d7e8818414 Further work on typestate. Handles expr_rec and expr_assign now.
Also changed the ts_ann field on statements to be an ann instead,
which explains most of the changes.

As well, got rid of the "warning: no type for expression" error
by filling in annotations for local decls in typeck (not sure whether
this was my fault or not).

Finally, in bitv, added a clone() function to copy a bit vector,
and fixed is_true, is_false, and to_str to not be nonsense.

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.)

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.

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.
