Introduce VTAny as `isOverloaded = true`. ValueType.isOverloaded` is used for;

- Define `iPTRAny`, `vAny`, `fAny`, and `Any`
- Reflect `ValueType.isOverloaded` to `LLVMType.isAny` in `Intrinsics.td`
- (Planninig) Reflect the condition to `MVT::isOverloaded()`

Introduce some fields in `ValueType`

- isInteger
- isFP
- isVector
- isScalable
- nElem
- ElementType

Introduce `VTVec<int nelem, ValueType elt, int value>` to represent
the element type. VTVec.Size may be calculated by `!mul(nelem, elt.Size)`.

Introduce `list<ValueType> ValueTypes` as convention for lookup.
