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.

4d71285c93 Implement quasi-quotes in more macro form: #ast{...}. 
The #(...) form is still supported for now.

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.

099290bc73 When replacing $(...) with $0 preserve spacing for better error messages. 
That is:
  x + $(foo) + y
becomes:
  x + $0     + y
not:
  x + $0 + y

e5d095d67e Change option::t to option 
Now that core exports "option" as a synonym for option::t, search-and-
replace option::t with option.

The only place that still refers to option::t are the modules in libcore
that use option, because fixing this requires a new snapshot
(forthcoming).

present in the source.  All have been changed to the equivalent
if/then/else expression.

b3f06c7d54 Stop passing spans to middle::trans functions that don't need them 
Removes a bunch of (eventually) unused arguments. Makes span passing to debuginfo
explicit, instead of relying on the (usually incorrect) spans held in the contexts.

87b064b249 First stab at operator overloading 
When no built-in interpretation is found for one of the operators
mentioned below, the typechecker will try to turn it into a method
call with the name written next to it. For binary operators, the
method will be called on the LHS with the RHS as only parameter.

Binary:

    +   op_add
    -   op_sub
    *   op_mul
    /   op_div
    %   op_rem
    &   op_and
    |   op_or
    ^   op_xor
    <<  op_shift_left
    >>  op_shift_right
    >>> op_ashift_right

Unary:

    -   op_neg
    !   op_not

Overloading of the indexing ([]) operator isn't finished yet.
