Do type promotion for short
...
fold_constants used to do this when it was overly aggressive. Fixes the
ICE when accessing an array in a struct via a pointer.

Add a test for accessing an array in a struct

That's accessed via a pointer. Whee. However, at this stage, the problem
is really a promotion issue for short -> integer.

Remove some weird dereference code

Make initialized globals non-constant
...
This is for modern code. Traditional code still treats initialized
globals as constant and nosave. This will make a bit of a mess of
modern code that expects traditional behavior.

Simplify fold_constants
...
While this does break automatic type promotion, it does stop
fold_constants recursing through complex expressions: only the top level
expression needs to be folded, and then only if both sides are actually
constant.

Start work on simple names in symbol tables
...
I don't remember what the goal was (stopped working on it eight months
ago), but some possibilities include:
- better handling of nil (have trouble with assigning into struts)
- automatic forward declarations ala C# and jai (I was watching vids
about jai at the time)
- something for pascal
- simply that the default symbol type should not be var (in which case,
goal accomplished)
