[CodeGen] Replace the reused stores' chain for extractelt expansion.
This fixes a subtle issue that was introduced in r205153. When reusing a store for the extractelement expansion (to load directly from it, inserting of going through the stack), later stores to the same location might have overwritten the data we were expecting to extract from. To fix that, we need to explicitly replace the chain going out of the reused store, so that later stores also have an explicit dependency on the generated element-extracting loads, and can't clobber them. rdar://20066785 Differential Revision: http://reviews.llvm.org/D8180 llvm-svn: 231721
