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).
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)
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.
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).
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pointless/outdated idioms from the code.
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.

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.
Issue #1177
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.
Issue #1054
This converts the AST fold into a resource that breaks it's own circular
reference (just a temporary workaround until GC), so that failure during fold
will unwind correctly.
