Clement Courbet	15488ff24b	[CodeGen] Fix the computation of the alignment of split stores. Summary: Right now the alignment of the lower half of a store is computed as align/2, which fails for unaligned stores (align = 1), and is overly pessimitic for, e.g. a 8 byte store aligned to 4 bytes.

Summary:
Right now the alignment of the lower half of a store is computed as
