521c16aadd Simplify the loop a bit

92581c24a3 There is no need for separate WriteSets and PhiNodeBlocks lists. It is just a 
work-list of value definitions.  This allows elimination of the explicit
'iterative' step of the algorithm, and also reuses temporary memory better.

036f1e7478 The PhiNodes 2D vector is only used during PHI node placement. It doesn't 
need to be an instance variable!

9157f041ab Two small cleanups/speedups: 
* Do not insert a new entry into NewPhiNodes during the rename pass if there are no PHIs in a block.
 * Do not compute WriteSets in parallel

0fa157127f * Minor cleanups 
* Eliminate the KillList instance variable, instead, just delete loads and
  stores as they are "renamed", and delete allocas when they are done
* Make the 'visited' set an instance variable to avoid passing it on the stack.

dd76acac3f A couple of minor code cleanups. 
Print literal doubles using ftostr instead of <<, because it yields higher precision numbers.

ed468e37a1 Type tables are now AbstractTypeUsers. This allows them to merge together 
constants as necessary due to type resolution.  With this change, the
following spec benchmarks now link: 176.gcc, 177.mesa, 252.eon,
253.perlbmk, & 300.twolf.  IOW, all SPEC INT and FP benchmarks now link.

7685ac8d35 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.

TestRunner tests).
This makes creating the new test database class easier to implement.

8ef852f4ea 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.
