Summary: MergedLoadStoreMotion::mergeStores is using some heuristics to limit the amount of stores that it tries to sink (see MagicCompileTimeControl in MergedLoadStoreMotion.cpp). The heuristic involves counting the number of instructions in one of the basic blocks that is part of the transformation. We now ignore dbg intrinsics when counting instruction for the MagicCompileTimeControl heuristic. This to make sure that the amount of stores that are sunk doesn't depend on the amount of debug information (if -g is used or not).
