9568568b75 - Clean up interface to Sparc register handling a bit: 
- Eliminate Sparc*Order classes, moving contents to Sparc*Class classes
   - get register name methods now return const char * const pointers instead
     of std::string's.
   - Added file header comments to SparcRegClassInfo.(cpp|h)
   - Moved BIG constant arrays out of SparcRegClassInfo.h, into
     SparcRegInfo.cpp.  This should allow a LOT of std::string constructors to
     not have to be called.

8b170945ea New functionality for instcombine: 
* New ReplaceInstUsesWith function to factor out tons of common code
     This needs to be used more in the future still, but it's a good start
   * New InsertNewInstBefore to allow multi-instruction replacements
   * Change getMaxValue functions to isAllOnesValue function, which doesn't
     have to CREATE/lookup a new constant.  Also the name is accurate
   * Add new isMaxValue, isMinValue, isMaxValueMinusOne, isMinValuePlusOne
     functions:  This should be moved to Constant* classes eventually
   * Implement xor X, ALLONES -> not X
   * Fold ALL setcc's of booleans away
   * Handle various SetCC's for integers against values at the end of their
     ranges, possibly off by one.  This implements the setcc-strength-reduce.ll
     testcase.

aaeee75af8 This file implements the top-down propagation pass for data structure graphs. 
Also, we now use a separate globals graph to hold externally visible nodes.
This changes both the bottom-up and top-down propagation so that
globals and other external objects do not have to appear in every
function, but only in functions in which they are referenced or
they can be used to access something else that is referenced.

c188eeb08c Cleanup ConstantExpr handling: 
* Correctly delete TypeHandles in AsmParser.  In addition to not leaking
   memory, this prevents a bug that could have occurred when a type got
   resolved that the constexpr was using
 * Check for errors in the AsmParser instead of hitting assertion failures
   deep in the code
 * Simplify the interface to the ConstantExpr class, removing unneccesary
   parameters to the ::get* methods.
 * Rename the 'getelementptr' version of ConstantExpr::get to
   ConstantExpr::getGetElementPtr

  basic blocks, but we DO want to drop references of dead instructions,
  so we factor the common code out to a new method.

other subclasses (that discriminate by type) have to check that it
is also not a ConstantExpr.

76ee6f70ea Significant changes to correctly spill CC registers and to correctly 
handle conditional move instructions:
-- cpMem<->Reg functions now support CC registers (int and FP) correctly.
   Also, cpMem<->Reg functions now return a vector of machine instructions.
-- 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.

Other changes:
-- Added several get{Class,Type} functions.
-- Added unified-to-local register number conversion.
-- class MachineCodeForBasicBlock is now an annotation on BasicBlock.
-- Suggest/Color methods may modify the MachineInstr (and always did),
   so don't make that argument const!
-- Caller-saving code doesn't need its special purpose code for
   handling CC registers since cpMem<->Reg handle those correctly now.

7a4be9580e Moved class MachineCodeForBasicBlock to MachineCodeForBasicBlock.{cpp,h}. 
An (explicit or implicit) operand may now be both a def and a use.
Also add a set of regs used by each instruction.
dump() no longer takes an optional argument, which doesn't work in gdb.

because operands may be modified directly to set register.
