8fd9986f0f Forbid classes with no fields
Classes with no fields don't really make sense, so forbid them
(just as records with no fields aren't allowed). Closes #2509

868e3f9180 Don't try to keep locals off of the stack. Closes #2408.
There were bugs in the code path for initialization of non-spilled
locals, the code-path is hit approximately never, and mem2reg can do
it for us.
I think this will let us kill spill_map.

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.
