[PATCH] D10905: move DAGCombiner's allowableAlignment() helper function into the TLI

Patch updated:

1. Changed implementation of allowsMemoryAccess() to check ABI alignment first and assume that ABI alignment is fast.
2. Added DataLayout as parameter because it's no longer available from TargetLowering.
