Sanjay Patel 75a2ce3271 [x86] extend machine combiner reassociation optimization to SSE scalar adds
Extend the reassociation optimization of http://reviews.llvm.org/rL240361 (D10460)
to SSE scalar FP SP adds in addition to AVX scalar FP SP adds.

With the 'switch' in place, we can trivially add other opcodes and test cases in
future patches.
