While working on the pool allocator, I noticed that basicaa is failing a scary
number of simple cases.  Someday when I get a chance to work on it again, this
testcase should be corrected.

Checking in Chris's suggestions:
Added assert() to ensure symbol table is well formed.
Added code to remember the value that was found; resolving types can change
the symbol table and invalidate the value of the iterator.
Added comments to the ResolveTypes() function (mainly for my own benefit).
Please feel free to correct the comments if they are not accurate.

Modified build rules so that a messages appears before and after linking.
This helps to disambiguate when linking begins and when the library/program

This is sort of as preference thing, so feel free to modify/revert the change.

Significantly simplify constant emission by unifying the stuff which used to build up

All DSGraphs keep a reference to the targetdata they are created with.  This is

eliminates a crash.
