cb2f43cbf4 Stop normalizing patterns 
The check for whether a pat_ident is a variant or a binding
is simple and fast. Normalizing patterns again and again is
slow and error-prone (several places were forgetting to do it).

ffd50b9cdf Make the various from_str functions return options 
So that they can be used with user input without causing task
failures.

2299d204e4 Further work on resolving and typechecking classes 
Class tests aren't working yet, but they fail a little later :-)

Also, make the parser correctly set a constructor's result type to
its enclosing class type.

67cc89f38d Rewrite exhaustiveness checker 
Issue #352
Closes #1720

The old checker would happily accept things like 'alt x { @some(a) { a } }'.
It now properly descends into patterns, checks exhaustiveness of booleans,
and complains when number/string patterns aren't exhaustive.

d6d7134c37 When parsing a source string, fail when the entire string is not parsed. 
(For now only fail when parse_from_source_str is used to avoid
possible compatibility problems; parse_expr_from_source_str still
does not check.)

Closes #1728

Comments out a section of debuginfo.rs. This code was already broken
(only being called when --xg was passed, and only working on trivial
programs).

e0fa5cd2ed Self types for ifaces 
This allows a 'Name:' to appear in front of an iface declaration's
name, which will cause 'Name' to refer to the self type (with the same
number of type parameters as the iface has) in the method signatures
of the iface. For example:

    iface F: functor<A> {
        fn fmap<B>(f: fn(A) -> B) -> F<B>;
    }

5c42e3df9c Allow non-semicolon-requiring expressions to be followed by .field 
There is no valid expression that starts with a dot token (.5 is a number token),
so this introduces no ambiguities.

b7ec2488ff Fix macro backtraces. 
In addition add information about the macro doing the expansion, and
move the printing of the expansion backtrace from codemap::span_to_str
to the diagnostic code.  The backtrace is now more verbose and
includes information on the macro doing the expansion, in addition to
the expansion site.

f3343b3571 Beginnings of front-end support for classes 
Added class support to the parser, prettyprinter, fold, and visit.
(See Issue 1726.)

This is WIP -- the test case is xfailed, and attempting to compile
it will error out in resolve.
