This patch detects consecutive vector loads using the existing EltsFromConsecutiveLoads() logic. This fixes: http://llvm.org/bugs/show_bug.cgi?id=22329 This patch effectively reverts the tablegen additions of D6492 / http://reviews.llvm.org/rL224344 ...which in hindsight were a horrible hack. The test cases that were added with that patch are simply modified to load from varying offsets of a base pointer. These loads did not match the existing tablegen patterns. A happy side effect of doing this optimization earlier is that we can now fold the load into a math op where possible; this is shown in some of the updated checks in the test file.
