To prepare the refactoring on D80364 <https://reviews.llvm.org/D80364>, intrinsics interested should be specified with the alignment on the return pointer. With this patch, `amdgcn.dispatch.ptr` is defined as follows

  def int_amdgcn_dispatch_ptr :
    Intrinsic<[LLVMQualPointerType<llvm_i8_ty, 4>], [],
    [Align<-1, 4>, IntrNoMem, IntrSpeculatable]>;


- This enable specifying the alignment on the return value as well as parameters.
