Add a bit to TargetInfo to specify that vectors are element-aligned rather than naturally aligned. This is needed to match DirectX's Data Layout in LLVM. Note that this removes the `Opts.HLSL` early exit from `checkDataLayoutConsistency` so that we actually get these checks when compiling HLSL. This check looks like it was put there because of similarity between OpenCL and HLSL, but it isn't actually necessary. Resolves #123968
