0e2cf7606d Several fixes: 
(1) Applied patch from Casey to implement iterator::operator= correctly:
    it should use a pointer, not a reference.
(2) Added operators == and !=, and method all().
(3) Important bug fix: excess bits need to be ignored in operations
    like ==, count(), and all().  We do this by ensuring excess bits
    in the last bitset are always 0.

35880f394f Instead of checking op.getType() against MO_VirtualRegister and 
MO_MachineRegister, we no longer distinguish Virtual vs. Machine registers
externally, they're ALL registers, all equal.

Registers are only differentiated whether they are >=
MRegisterInfo::FirstVirtual or not.

1617e6c997 SSARegMap -- the mapping between SSARegisters and their RegisterClasses, which 
imply types of SSA Registers. This is on a per-function basis, so the
MachineFunction contains the SSARegMap, and has accessor functions to it.

6559bb96a9 include/llvm/CodeGen/MachineInstrBuilder.h: Add addClobber() inline 
convenience method.  Fix typo in comment.
lib/Target/X86/InstSelectSimple.cpp: Explicitly specify some implicit uses.
 Use MOVZX/MOVSX instead of MOV instructions with sign extend instructions.
 Take out LEAVE instructions.
 32-bit IDIV and DIV use CDQ, not CWQ (CWQ is a typo).
 Fix typo in comment and remove some FIXME comments.
lib/Target/X86/Printer.cpp: Include X86InstrInfo.h and llvm/Function.h.
 Add some simple code to Printer::runOnFunction to iterate over
  MachineBasicBlocks and call X86InstrInfo::print().
lib/Target/X86/X86InstrInfo.def: Make some more instructions with
 implicit defs "Void".  Add more sign/zero extending "move" insns
 (movsx, movzx).
lib/Target/X86/X86RegisterInfo.def: Add EFLAGS as a register.

fb39933b75 - Add support for an "auxillary" call site list 
- Original call sites are now never modified after construction by the local
  pass.
- DSGraph::cloneInto can now optionally not clone the call sites
- BUDataStructures no longer has a ton of book-keeping info for a broken
  implementation of the TD data structures

8f0a16eac6 This fixes all kinds of problems with array handling. There are still bugs to 
be fixed, but we are getting much closer now.

    * Make DSNode::TypeRec a full fledged DSTypeRec type.
    * Add methods used to update and access the typerecords elements
    * Add methods to query if and to cause a node to be completely folded
    * DSGraph construction doesn't use the allocation type for anything at all,
      now nodes get their type information based on how they are used.
    * Fixed a bug with global value handling introduced in the last checkin
    * GEP support is now much better, arrays are handled correctly.  The array
      flag is now updated in type records.  There are still cases that are not
      handled yet (we do not detect pessimizations), but getting much closer.
