* Reorganized typestate into several modules.
* Made typestate check that any function with a non-nil return type
returns a value. For now, the check is a warning and not an error
(see next item).
* Added a "bot" type (prettyprinted as _|_), for constructs like be, ret, break, cont, and
fail that don't locally return a value that can be inspected. "bot"
is distinct from "nil". There is no concrete syntax for _|_, while
the concrete syntax for the nil type is ().
* Added support to the parser for a ! annotation on functions whose
result type is _|_. Such a function is required to have either a
fail or a call to another ! function that is reached in all control
flow paths. The point of this annotation is to mark functions like
unimpl() and span_err(), so that an alt with a call to err() in one
case isn't a false positive for the return-value checker. I haven't
actually annotated anything with it yet.
* Random bugfixes:
* * Fixed bug in trans::trans_binary that was throwing away the
cleanups for nested subexpressions of an and or or
(tests: box-inside-if and box-inside-if2).
** In typeck, unify the expected type arguments of a tag with the
actual specified arguments.

This is preliminary version of the Rust compiler(s).
Source layout:
comp/ The self-hosted compiler
rt/ The runtime system
rt/rust_*.cpp - The majority of the runtime services
rt/isaac - The PRNG used for pseudo-random choices in the runtime
rt/bigint - The bigint library used for the 'big' type
rt/uthash - Small hashtable-and-list library for C, used in runtime
rt/{sync,util} - Small utility classes for the runtime.
test/ Testsuite (for both bootstrap and self-hosted)
test/compile-fail - Tests that should fail to compile
test/run-fail - Tests that should compile, run and fail
test/run-pass - Tests that should compile, run and succeed
test/bench - Benchmarks and miscellanea
Please be gentle, it's a work in progress.
