32f81a3469 Allow copy coalescing in more cases: if sum of node degrees is more than 
than #available regs, compute the sum excluding duplicates and if that
is less than #regs, go ahead and coalesce.
Add method IGNode::getCombinedDegree to count excluding duplicates.

abf055c698 Moving these files from Code/PreSelection to here. 
Original logs for PreSelection.cpp:

  revision 1.2
  date: 2002/09/17 23:50:32;  author: lattner;  state: Exp;  lines: +1 -3
  Don't put default parameter values into .cpp files, it breaks 3.x compilers

  revision 1.1
  date: 2002/09/16 15:31:13;  author: vadve;  state: Exp;
  New preselection pass that specializes LLVM code for a target machine,
  while remaining in legal portable LLVM form and preserving type
  information and type safety.

3e1f144a1d Make sure that we abort if an error happens as early as neccesary. Before 
it was possible for the passmanager to continue running passes after the
verifier even if the module was not well formed.

a6299345ee * Add capability to recognize alias properties of the following common cases: 
- A[c1] cannot alias A[c2] where constants c1 != c2
  - A[i] cannot alias B[j] if A & B are provably different arrays

This should help out array based codes.  For example, from bzip2 from spec,
3 additional loads can be GCSE'd, and _21_ additional loads can be LICMd due
to this change.

In a test example from the Spec GAP benchmark (vecffe.c), this change allows
_52_ additional loads to be GCSE'd and _224_ additional LICM'd loads.

Not bad for such a simple change.  Other testcases show no change at all
because they just don't use arrays.  Not too suprising there.

85af131d9e Unary Not (boolean and bitwise) is no longer a separate LLVM instruction 
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.

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.
