ilist of MachineInstr objects. This allows constant time removal and
insertion of MachineInstr instances from anywhere in each
MachineBasicBlock. It also allows for constant time splicing of
MachineInstrs into or out of MachineBasicBlocks.

MO_VirtualRegister but if the register number is one of a physical
register is it considered as a physical register.

I will observe that the concept of using WriteAsOperand is completely broken,
but then we all knew that, didn't we?

instead of randomly groping about inside its outEdges array.
Make SchedGraph::addDummyEdges() use getNumOutEdges() instead of
outEdges.size().
Get rid of ifdefed-out code in SchedGraph::buildGraph().

It's not clear why the code was looking for signed chars < 0, but it can't
matter to the assembler anyway, so the check goes away. This also fixes
compatibility with arrays of [us]byte that have constantexprs in them.
Also slightly restructure some code to be cleaner.

Using the SlotCalculator is total overkill for this file, a simple map
will suffice. Why doesn't this use the NameMangler interface?

implementation of a Target{RegInfo, InstrInfo, Machine, etc} now has a separate
header and a separate implementation file.
This means that instead of a massive SparcInternals.h that forces a
recompilation of the whole target whenever a minor detail is changed, you should
only recompile a few files.
Note that SparcInternals.h is still around; its contents should be minimized.

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.

* Restore registers *after* everything else to avoid any possible side effects
This fixes McCat-imp.

* There is now only one pass to print out assembly instead of two
* It is a FunctionPass
* The Module-level printing of globals is now in doFinalization() method of the
FunctionPass
* The code has been reformatted to follow LLVM coding standards
* Some comments, not all, were doxygenified
* Last but not least, the function to create an instance of this pass is also no
longer a method in the UltraSparc class.
