Owen Anderson b48783b091 Reapply r174343, with a fix for a scary DAG combine bug where it failed to differentiate between the alignment of the ... base point of a load, and the overall alignment of the load. This caused infinite loops in DAG combine with the original application of this patch. ORIGINAL COMMIT LOG: When the target-independent DAGCombiner inferred a higher alignment for a load, it would replace the load with one with the higher alignment. However, it did not place the new load in the worklist, which prevented later DAG combines in the same phase (for example, target-specific combines) from ever seeing it. This patch corrects that oversight, and updates some tests whose output changed due to slightly different DAGCombine outputs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174431 91177308-0d34-0410-b5e6-96231b3b80d8		2013-02-05 19:24:39 +00:00
