093faaabe1 Handle index expressions' callee IDs correctly 
Some code that handles unary and binary exprs' callee IDs was
    forgetting to handle the index expr case (since calls to
    user-defined index operators also have callee IDs). This was
    manifesting as an ICE in trans because when monomorphizing a
    function that had one of these operators in it (an index into a
    dvec, in the test case), the callee ID would be unbound to a type.

    Fixed it. Closes #2631.

77e6573929 Further work on integer literal suffix inference (#1425) 
In this commit:

  * Change the lit_int_unsuffixed AST node to not carry a type, since
    it doesn't need one

  * Don't print "(unsuffixed)" when pretty-printing unsuffixed integer
    literals

  * Just print "I" instead of "(integral)" for integral type variables

  * Set up trans to use the information that will be gathered during
    typeck to construct the appropriate constants for unsuffixed int
    literals

  * Add logic for handling int_ty_sets in typeck::infer

  * Clean up unnecessary code in typeck::infer

  * Add missing mk_ functions to middle::ty

  * Add ty_var_integral to a few of the type utility functions it was
    missing from in middle::ty

97bcb20244 Avoid some duplicated typechecking work 
There was a FIXME noting that ty::enum_variants and typeck::check::
check_enum_variants both call eval_const_expr. I tried refactoring the
code so that check_enum_variants does all the work and enum_variants
just looks up cached results, but this turned out not to be easy because
several ty functions call enum_variants and it might get invoked on an
enum before that enum item has been typechecked. Instead, I just made
check_enum_variants update the enum_var_cache so that enum_variants
will never call eval_const_expr twice on the same const.

6f95c79b95 Traverse types in reachability 
Issue 2526 showed a test case where a library exported only a type
that was a synonym for a class. Because the class's destructor wasn't
getting marked as reachable, its linkage was wrongly getting set to
"internal". The solution is for reachability to traverse types.

Closes #2526.

72360970fc Change trans::common::block to be a class 
And replace trans::common::block_parent with option<block>. To handle
the recursive self-reference in the block_ class, I had to add a
newtype-like enum "block" which is equivalent to @block_ -- which due
to an interaction with borrowck, resulted in having to change a few
functions in trans::base to take their block argument in ++ mode,
irritatingly enough (but not that irritatingly, since we're supposed to
get rid of modes).

f4fb0f9eea Handle regions correctly in class ctors and dtors 
Class ctors and dtors were always getting assigned the empty region
before, which meant a reference to the "self" region in a ctor argument
got resolved to a named region called "self" rather than the class's
self region, which led to a rather confusing error message as documented
in #2502.

Closes #2502

8972588583 Dereference classes with dtors only on a field access 
A class with a dtor has a different representation (a pair of a bit field
and a pointer to the class itself), and previously, the trans code
was selecting out the second field on any reference to a variable whose
type was a class with a dtor. This turned out to be wrong in the case where
a closure captures a variable with such a type. Changed the code to only
insert the field selection on a class field access.

ebde93861f Allow classes with dtors to be used before declaration 
get_item_val could generate an internal compiler error if a class with
a dtor was used before the class itself got translated, because it was
assuming that the dtor's node ID was always in the item_symbols table. Fixed
it to create a new symbol if necessary, and use it subsequently.

22a10f0e4a refactor region manip. to remove redundancy, get closer to fn subtyping 
also: remove "auto-mode-matching" for implemented interfaces, as it
is complex and interacts poorly with classes

e6b9db0884 refactor region manipulation routines to eliminate duplication 
fn subtyping is starting to work, but it's exposing bugs in the
code which checks for iface conformance, which doesn't properly
skolemize the self region

rather than the unchanged prestate.

ccc7651b48 In reachability, don't ignore nested items 
Reachability was considering nested items to be unreachable, which
was causing the bug in #2383. Once I fixed that, I also had to make
impl::make_impl_vtable instantiate methods where necessary, before
calling monomorphic_fn.

Closes #2383
