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.

4f105e4025 In resolve, visit the path in an iface ref 
Necessary to resolve any type arguments in a ref to a parameterized
iface. This meant that, for example:

class A implements B<int> { ...

didn't work before, because the "int" in B's argument wasn't getting
visited, and thus wasn't getting resolved. Now it works.

Partially addresses Issue #2288, but I also want to check that class
ty params can appear as the type arguments to ifaces (for example,

class A<T> implements B<T> {...

should work.)

See the test case I added (issue-2316-c) for a concrete example.

was using bitwise or instead of logical or when checking exports,
resulting in excessively eager evaluation. A one-line fix that took

This alignment is the "preferred" alignment of a type, which is not
necessarily the alignment the compiler will use when packing the
type into structures - that is the "ABI" alignment (in LLVM terms).

On x86, 64-bit ints have 8-byte preferred alignment, but 4-byte
ABI alignment.

- fix various small bugs:
  - we never checked that iface types were compatible when casting
    to an iface with `as`
  - we allowed nonsense like int<int>
  - and more! (actually that may be it)

Introduce syntax like:

to allow classes to implement ifaces. Casting classes to ifaces
is *not* yet supported. ifaces that a class implements are not
yet included in metadata.

The syntax is subject to change, and may go away completely if we
decide to use duck typing to relate classes with ifaces (see

c902eafa14 Convert old-style for loops to new-style 
Most could use the each method, but because of the hack used to
disambiguate old- and new-style loops, some had to use vec::each.

(This hack will go away soon.)

5a3875e998 Print "expected a record with field..." fields in the right order 
Because terr_record_mismatch was getting called by infer::flds,
which takes types a and b where it's trying to prove a <: b, the
expected and actual fields were switched. Fixed it. Closes #2094

c0d61795de wip: refactor repr of regions 
- we now distinguish bound/free parameters (see region-param
  test case for why this is necessary)
- we also track bounds on region variables
- also, restructure fold_ty() to have multiple variants without
  duplication instead of one overloaded folder.  This also allows
  for using block functions.

7aae7320db std: change time::timeval to be {sec: i64, usec: i32}. 
It's possible to have negative times if expressing time before 1970, so
we should use signed types. Other platforms can return times at a higher
resolution, so we should use 64 bits.

1f892dcb01 Monomorphize class constructors, support generic classes and class methods 
Allow class methods to have type parameters (this is a change from the
original classes proposal).

Add test cases for classes with type parameters, and classes with methods
that have their own type parameters.
