Thanks @huntergr , I think this interface looks really nice. LGTM!



================
Comment at: llvm/include/llvm/IR/DataLayout.h:456
+  TypeSize getTypeStoreSize(Type *Ty) const {
+    auto BaseSize = getTypeSizeInBits(Ty);
+    return { (BaseSize.getKnownMinSize() + 7) / 8, BaseSize.isScalable() };
----------------
nit: use TypeSize instead of auto.


================
Comment at: llvm/include/llvm/IR/DataLayout.h:622
   case Type::LabelTyID:
-    return getPointerSizeInBits(0);
+    return TypeSize::Fixed(getPointerSizeInBits(0));
   case Type::PointerTyID:
----------------
Nice, I like the interface of `TypeSize::Fixed()` for fixed-size types.


================
Comment at: llvm/lib/IR/Instructions.cpp:2990
   // Get the bit sizes, we'll need these
-  unsigned SrcBits = SrcTy->getPrimitiveSizeInBits();   // 0 for ptr
-  unsigned DestBits = DestTy->getPrimitiveSizeInBits(); // 0 for ptr
+  auto SrcBits = SrcTy->getPrimitiveSizeInBits();   // 0 for ptr
+  auto DestBits = DestTy->getPrimitiveSizeInBits(); // 0 for ptr
----------------
nit: auto -> TypeSize ?
