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.

9ff5ba085d Fix bad line printing for parse errors
The code that extracted lines from partially-parsed files
was broken.

6627890f6b Support 'alt check' syntax
It is only a way to flag an alt as intentionally non-exhaustive right now.

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.)

a803a14b56 Bug fix to accept $ in 0th pos, (ie #ast{$(x) + ...}).
Note: part from Niko Matsakis commit: rewrite assert to accept a $ in
0th pos.

a08e589390 Handle built-in typenames in the resolve pass, rather than in parser
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.

9090a5c03b Store info about file "substr".
That is when a string that is part of a file needs to be parsed for a
reason, record that the string is a substr of the file rather than
using "<anon>" or "-" as the file name.  This will eventually allow
pointing to the right location, for now it just uses a more
meaningful string for the filename.

1c91fb4d91 Don't rely on filename to get a file from the filemap
as there may be more than one filemap with the same filename (in the
case of stdin for instance).  This involved storing a pointer to the
filemap rather than the filename in location info such as
codemap::pos.
