Discriminator enum (for isa<>, dyn_cast<>, et al.)
This enum is laid out by a preorder traversal of the inheritance hierarchy, and does not contain an entry for abstract classes, as per the recommendation in docs/HowToSetUpLLVMStyleRTTI.rst.
We also explicitly include "first" and "last" values for each interior node of the inheritance tree, to make it easier to read the corresponding classof().
We could pack these a bit tighter by not having the IK_FirstXXXInit and IK_LastXXXInit be their own values, but that would degrade readability for really no benefit.

This method is used to implement the bitrange selection operator.
Given an initializer, it selects the specified bits out, returning them as a new init of bits type. If it is not legal to use the bit subscript operator on this initializer, return null.
Reimplemented in llvm::IntInit, llvm::BitsInit, and llvm::TypedInit.
This virtual function converts to the appropriate Init based on the passed in type.
Implemented in llvm::DagInit, llvm::DefInit, llvm::VarBitInit, llvm::ListInit, llvm::CodeInit, llvm::StringInit, llvm::IntInit, llvm::BitsInit, llvm::BitInit, llvm::UnsetInit, and llvm::TypedInit.
Referenced by llvm::UnOpInit::Fold(), llvm::BinOpInit::Fold(), llvm::TernOpInit::Fold(), llvm::TernOpInit::resolveReferences(), and llvm::RecordVal::setValue().
This method is used to implement the list slice selection operator.
Given an initializer, it selects the specified list elements, returning them as a new init of list type. If it is not legal to take a slice of this, return null.
Reimplemented in llvm::ListInit, and llvm::TypedInit.
