* Only load incoming arguments into virtual registers once at the
    beginning of the function
  * Assign different virtual registers to each reference to constants/globals

Fix some bugs in use of MBB vs. BB and iterators that are invalidated before
we use them.

2f2cf00a9f Cleaned up the code: factored out switch/case into a separate function, put
constants in an array for quick lookup. Stole the idea from elsewhere in
Jello.

34ad176df5 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.

 displacement (whew!) due to Chris.

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