[PATCH] D13294: LEA code size optimization pass (Part 1): Remove redundant address recalculations

[Andrey Turetskiy via llvm-commits]

Added more tests.
"The size of the displacement exceeds 4-bytes." - this case is the only one remaining uncovered. I wasn't able to force the compiler to use such big address displacement (If address has a big displacement it's stored into a register and than used through it). Not sure if this is possible without changing compiler sources.
