addConstantPoolEntryAddr - Map a Constant Pool Index to the address where its associated value is stored. When relocations are processed, this value will be used to resolve references to the constant.

addIndirectSymAddr - Add a mapping from address of an emitted symbol to its indirect symbol address.

addJumpTableBaseAddr - Map a jump table index to the address where the corresponding inline jump table is emitted. When relocations are processed, this value will be used to resolve references to the jump table.
