Fix for PR14824: "Optimization arm_ldst_opt inserts newly generated instruction vldmia at incorrect position". Patch introduces memory operands tracking in ARMLoadStoreOpt::LoadStoreMultipleOpti. For each register it keeps the order of load operations as it was before optimization pass. It is kind of deep improvement of fix proposed by Hao: http://llvm.org/bugs/show_bug.cgi?id=14824#c4 But it also tracks conflicts between different register classes (e.g. D2 and S5).
