6a8a9b4413 Continue Alkis's int64_t cleanup. This makes all of the immediate related 
methods take an int or unsigned value instead of int64_t.

Also, add an 'addImm' method to the MachineInstrBuilder class, because the
fact that the hardware sign or zero extends it does not/should not matter
to the code generator.  Once the old sparc backend is removed the difference
can be eliminated.

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? :)

pair, and look up varargs in the execution stack every time, instead of

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).

switch statements in the constructors and simplifies the

(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.

f32f56862a Now that all of the derived types have disciplined interfaces, we can eliminate 
all of the ad-hoc storage of contained types.  This allows getContainedType to
not be virtual, and allows us to entirely delete the TypeIterator class.

4ff0b9636d Substantially improve the DSA code by removing 'forwarding' nodes from 
DSGraphs while they are forwarding.  When the last reference to the forwarding
node is dropped, the forwarding node is autodeleted.  This should simplify
removeTriviallyDead nodes, and is only (efficiently) possible because we are
using an ilist of dsnodes now.

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.
