*	[DAGCombine] Fix alignment for offset loads/stores	David Green	2018-06-21	1	-0/+25
	The alignment parameter to getExtLoad is treated as a base alignment, not the alignment of the load (base + offset). When we infer a better alignment for a Ptr we need to ensure that it applies to the base to prevent the alignment on the load from being wrong. This fixes a bug where the alignment could then be used to incorrectly prove noalias between a load and a store, leading to a miscompile.
