This introduces a small regression on the generated code
quality in the case we are just computing addresses, not
loading values.

Will work on it and on X86-64 support.

the frame reference. This will help post-RA scheduling determine
that spills to distinct stack slots are independent.

- Remove calls to copyKillDeadInfo which is an N^2 function. Instead, propagate kill / dead markers as new instructions are constructed in foldMemoryOperand, convertToThressAddress, etc.
- Also remove LiveVariables::instructionChanged, etc. Replace all calls with cheaper calls which update VarInfo kill list.

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.
