06dbcc0540 Minor random speedup: make Constant::getNullValue only call ConstantFOO::get 
once!

18c3f42894 This checkin basically amounts to a complete rewrite of the type-resolution 
machinery.  This dramatically simplifies how things works, removes irritating
little corner cases, and overall improves speed and reliability.

Highlights of this change are:

1. The exponential algorithm built into the code is now gone.  For example
   the time to disassemble one bytecode file from the mesa benchmark went
   from taking 12.5s to taking 0.16s.
2. The linker bugs should be dramatically reduced.  The one remaining bug
   has to do with constant handling, which I actually introduced in
   "union-find" checkins.
3. The code is much easier to follow, as a result of fewer special cases.
   It's probably also smaller.  yaay.

8a261626fc Changed all of these tests to be TestRunner tests (or, at least they can be 
TestRunner tests).
This makes creating the new test database class easier to implement.

101d5058cb These methods are dead, remove them. Because the bodies will soon be 
ressurected, just ifdef them out for now.

e63831e3bf Renamed these tests so that they don't contain extra periods. 
This interferes with QMTest and the new test database.

85444d1dbd Dramatically simplify DerivedType::refineAbstractTypeToInternal 
This makes use of the new PATypeHolder's to keep types from being deleted
prematurely, instead of the wierd "self reference" garbage.  This is easier
to understand and more efficient as well.

b217f24289 Make the PATypeHolder use a simple union-find implementation to handle 
merging of types.  This makes it MUCH more efficient than before, also
making things simpler.

62331c44ab There is no need for BytecodeParser to be an AbstractTypeUser. Instead, it 
can just use PATypeHolders

83856d0df1 There is no reason for Value to be an AbstractTypeUser. This just makes things 
significantly more complete.  Instead, just make DerivedType's AbstractTypeUser's,
and make Value contain a PATypeHolder.

564dbbf299 There is no reason for Value to be an AbstractTypeUser. This just makes things
