but was in the Sparc directory.  This is in a new function: GetMemInstArgs.

but is instead implemented with XOR.  Note that the InstrForest opLabels
for Not and BNot remain the same, i.e., the XOR is recognized and
represented as a (boolean or bitwise) Not when building the instruction
trees.  But these tree nodes are now binary, not unary.

* Removed extraneous #includes
* Fixed file headers to be consistent with the rest of LLVM
* Other minor fixes

- Cleaned up the interface to AnalysisUsage to take analysis class names
   instead of ::ID's.
 - Pass::getAnalysis<> now no longer takes an optional argument

Fix 2 bugs in FoldGetElemChain so index vector is not modified
when no GEPs are folded in, and so a hasLeadingZero is computed
only for the last folded GEP, not the one after that if any.

  is platform independant afterall.
* Object orientize the functions, cleanup code a bit.  Instead of static
  global functions, the helpers for instruction selection are now part of
  the InstructionSelection Pass class.

handle conditional move instructions:
-- cpMem<->Reg functions now support CC registers (int and FP) correctly.
-- Scratch registers must be explicitly provided to cpMem<->Reg when
   needed, since CC regs need one to be copied to/from memory.
-- CC regs are saved to a scratch register instead of stack.
-- All regs used by a instruction are now recorded in MachineInstr::regsUsed,
   since regs used to save values *across* an instruction are not obvious
   either from the operands or from the LiveVar sets.
-- An (explicit or implicit) operand may now be both a def and a use.
   This is needed for conditional move operations.
   So an operand may need spill code both before and after the instruction.
-- class MachineCodeForBasicBlock is now an annotation on BasicBlock.

because operands may be modified directly to set register.
Also, class MachineCodeForBasicBlock is now an annotation on BasicBlock.

Moved here from MachineInstr.cpp to make it an annotation on BasicBlock.

so additional dep. edges have to be added.
This was needed to correctly handle conditional move instructions!
MachineCodeForBasicBlock is now an annotation on BasicBlock.
Renamed "earliestForNode" to "earliestReadyTimeForNode".
