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.

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

aa2efc05ea Adding shared_arc to hide some of the tedium of sharing an arc between tasks. 
Also added some asserts and logging to trans.

Modified graph500 to use the shared_arc, but this unfortunately doesn't work due to #2444.

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.)
