c230978a82 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... :)

7c78afefe9 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).

To get a zero value, we must use T().  It's C++ wonderful? :)

9d20b71eca Represent va_list in interpreter as a (ec-stack-depth . var-arg-index) 
pair, and look up varargs in the execution stack every time, instead of
just pushing iterators (which can be invalidated during callFunction())
around.  (union GenericValue now has a "pair of uints" member, to support
this mechanism.) Fixes Bug 234.

743d0a1f83 Refactor rewinding code for finding the first terminator of a basic 
block into MachineBasicBlock::getFirstTerminator().

This also fixes a bug in the implementation of the above in both
RegAllocLocal and InstrSched, where instructions where added after the
terminator if the basic block's only instruction was a terminator (it
shouldn't matter for RegAllocLocal since this case never occurs in
practice).

890f92328d Move MOTy::UseType enum into MachineOperand. This eliminates the 
switch statements in the constructors and simplifies the
implementation of the getUseType() member function. You will have to
specify defs using MachineOperand::Def instead of MOTy::Def though
(similarly for Use and UseAndDef).

39a0d5c112 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.

2cca3008e8 One of the 'annoying' things about ilists is that the iterators don't behave 
quite the same as for non-intrusive lists of pointers to nodes.  To support
transitioning code bases, add a new 'compatibility' iterator.

e88280a422 Add option to join live intervals. Two intervals are joined if there 
is a move between two registers, at least one of the registers is
virtual and the two live intervals do not overlap.

This results in about 40% reduction in intervals, 30% decrease in the
register allocators running time and a 20% increase in peephole
optimizations (mainly move eliminations).

The option can be enabled by passing -join-liveintervals where
appropriate.

26bfc08b80 Add coalescing to register allocator. A hint is added to each interval 
which denotes the register we would like to be assigned to (virtual or
physical). In register allocation, if this hint exists and we can map
it to a physical register (it is either a physical register or it is a
virtual register that already got assigned to a physical one) we use
that register if it is available instead of a random one in the free
pool.

2cffeec014 Add a new AliassetTracker::remove method. Because we need to be able to remove 
a pointer from an AliasSet, maintain the pointer values on a doubly linked
list instead of a singly linked list, to permit efficient removal from the
middle of the list.

4d7af65903 Change interface of MachineOperand as follows: 
a) remove opIsUse(), opIsDefOnly(), opIsDefAndUse()
    b) add isUse(), isDef()
    c) rename opHiBits32() to isHiBits32(),
              opLoBits32() to isLoBits32(),
              opHiBits64() to isHiBits64(),
              opLoBits64() to isLoBits64().

This results to much more readable code, for example compare
"op.opIsDef() || op.opIsDefAndUse()" to "op.isDef()" a pattern used
very often in the code.
