Sanjay Patel 05d5e213c4 merge consecutive stores of extracted vector elements (PR21711) ... This is a 2nd try at the same optimization as http://reviews.llvm.org/D6698. That patch was checked in at r224611, but reverted at r225031 because it caused a failure outside of the regression tests. The cause of the crash was not recognizing consecutive stores that have mixed source values (loads and vector element extracts), so this patch adds a check to bail out if any store value is not coming from a vector element extract. This patch also refactors the shared logic of the constant source and vector extracted elements source cases into a helper function.
