0efb50761d Add method IGNode::getCombinedDegree to count the sum of the degrees
of two nodes, excluding duplicates.

d55697cf13 Added class MachineOptInfo as interface to target-specific
routines supporting machine code optimization.
Also added method MachineInstrInfo::getNOPOpCode().

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.

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.
