e76fdeb3a6 Change the type for the macro body to also store the span. 
Note: the body is the part of the macro syntax between the {}.

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).

fba35e1a3c Require alts to be exhaustive 
middle::check_alt does the work. Lots of changes to add default cases
into alts that were previously inexhaustive.

c5e03e0e59 Keep source file around after parsing. 
Specifically box the string (to avoid unnecessary copies) and store it
in codemap::filemap.

Remove the hack in driver::diagnostic that rereads the source from the
file and instead just get the source from the filemap.

(This commit is also a prerequisite for issue #1612)

4795e19d6d When replacing a pattern variable in macro expansion use the span of 
the replacement and not the span of the pattern variable.

Fixes issue #1448, and #1387.

20ab47fe49 Allow ast_fold_precursor to change the span. 
This involved changing the prototype for the callbacks to thread the
span though.  A wrapper function, fold::wrap, can be used to wrap the
old style callbacks.

The next commit will remove support for this syntax.

efb9df1ebd Make driver::session::session no longer an object 
Rather, it is now a struct where properties like opts are accessed
directly, and the error-reporting methods are part of a static impl
(with the same name as the type).

34d7f05292 Major clean-up of std::io 
Use ifaces instead of objs, stop wrapping everything in two (or three)
layers of no-value-added indirection, and remove some of the more
pointless/outdated idioms from the code.

e3eca9174b Change literal representation to not truncate 
Also shuffles around the organization of numeric literals and types,
separating by int/uint/float instead of machine-vs-non-machine types.
This simplifies some code.

f6491bb426 Update stdlib, compiler, and tests to new kind system 
This involved adding 'copy' to more generics than I hoped, but an
experiment with making it implicit showed that that way lies madness --
unless enforced, you will not remember to mark functions that don't
copy as not requiring copyable kind.

7114702496 Change the way block calls are parsed, mark them as block-calls. 
This makes it possible to omit the semicolon after the block, and will
cause the pretty-printer to properly print such calls (if
pretty-printing of blocks wasn't so broken). Block calls (with the
block outside of the parentheses) can now only occur at statement
level, and their value can not be used. When calling a block-style
function that returns a useful value, the block must be put insde the
parentheses.
