lib/Target/X86/InstSelectSimple.cpp: Start counting arguments with 2,
 because arguments start two stack slots off of EBP. Break out of the
 for loop once the argument is found. Increment the counter at the end
 of the loop instead of the beginning. Use addRegOffset and compute
 the scale * index part at compile time instead of using the fancy
 load instruction. Just because an instruction set has wacky addressing
 modes doesn't mean we ought to use them (at least, if you believe Dave
 Patterson).

lib/Target/X86/X86InstrBuilder.h: Add some comments.

test/Regression/Jello/test-loadstore.ll:  Let main return int 0.

InstSelectSimple.cpp:  Give promote32 a comment.  Add initial
 implementation of getReg() for arguments.

MachineCodeEmitter.cpp: Fix using EBP with index, scale and no
 displacement (whew!) due to Chris.

Printer.cpp: Fix printing out index and scale in memory references.

Implement ConstantPointerRefs
Treat long/ulongs as if they were integers.  A hack, but an effective one

InstSelectSimple.cpp: Add stub implementation of visitFreeInst.
 Add comments that mention how we are failing to implement malloc/free.
 Add initial implementation of visitAllocaInst.

X86TargetMachine.cpp: Include llvm/Transforms/Scalar.h.
 Add LowerAllocations pass before instruction selection.

jello/Makefile: Add scalaropts.a.
