12e1831ffe Change the call graph class to have TWO external nodes, making call graph 
SCC passes much more useful.  In particular, this should fix the incredibly
stupid missed inlining opportunities that the inliner suffered from.

b78f8498f0 TargetCacheInfo has been removed; its only uses were to propagate a constant 
(16) into certain areas of the SPARC V9 back-end. I'm fairly sure the US IIIi's
dcache has 32-byte lines, so I'm not sure where the 16 came from. However, in
the interest of not breaking things any more than they already are, I'm going
to leave the constant alone.

176413cedb Fix the "partial pool allocator" on em3d and others. The problem is that 
DSNodes, unlike other GraphTraits nodes, can have null outgoing edges, and
df_iterator doesn't take this into consideration.  As a workaround, the
successor iterator now handles null nodes and 'indicates' that null has
no successors.

34977159b3 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.

f7cc508c0a 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... :)

9b103024ef 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).

7f7d70a53c 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).

f32239a5c6 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.
