[DAGCombiner] handle more store value forwarding
When lowering calls on target like PPC, some stack loads
will be generated for by value parameters. Node CALLSEQ_START
prevents such loads from being combined.
Suggested by @RolandF, this patch removes the unnecessary
loads for the byval parameter by extending ForwardStoreValueToDirectLoad
