Make the DataLayout string always hold a vector alignment of 8 bytes, regardless of the vector ABI. This makes the datalayout depend only on the target triple which is the general expectation (in assertions). On older architectures where vectors use the natural alignment (16 bytes), the front end will maintain the same behavior and produce an overalignment compared to the datalayout.
