New revision based on previous comments. I refactored the logic used on isFPImmLegal to evaluate whether to materialize the FP constant or not by adding a new function on common aarch64 code, AArch64_AM::getExpandImmCost. To avoid code replication I refactored the code by moving some definitions from AArch64ExpandPseudoInsts.cpp.
