Annotations are evil. This makes Value not derive from Annotable, which makes
...
all dynamically allocated LLVM values 4 bytes smaller, eliminate some vtables, and
make Value's destructor faster.
This makes Function derive from Annotation now because it is the only core LLVM
class that still has an annotation stuck onto it: MachineFunction.
MachineFunction is obviously horrible and gross (like most other annotations), but
will be the subject of refactorings later in the future. Besides many fewer
Function objects are dynamically allocated that instructions blocks, constants,
types, etc... :)

Fix a bug in the densemap that was killing the local allocator, and probably

other clients. The problem is that the nullVal member was left to the default
constructor to initialize, which for int's does nothing (ie, leaves it unspecified).

Too many changes in one commit:
...
1. LiveIntervals now implement a 4 slot per instruction model. Load,
Use, Def and a Store slot. This is required in order to correctly
represent caller saved register clobbering on function calls,
register reuse in the same instruction (def resues last use) and
also spill code added later by the allocator. The previous
representation (2 slots per instruction) was insufficient and as a
result was causing subtle bugs.
2. Fixes in spill code generation. This was the major cause of
failures in the test suite.
3. Linear scan now has core support for folding memory operands. This
is untested and not enabled (the live interval update function does
not attempt to fold loads/stores in instructions).
4. Lots of improvements in the debugging output of both live intervals
and linear scan. Give it a try... it is beautiful :-)
In summary the above fixes all the issues with the recent reserved
register elimination changes and get the allocator very close to the
next big step: folding memory operands.
