Fabian Ritter 8adcc8a669 [SelectionDAG] Introduce ISD::PTRADD (#140017) ...

This opcode represents the addition of a pointer value (first operand)
and an integer offset (second operand). PTRADD nodes are only generated
if the TargetMachine opts in by overriding
TargetMachine::shouldPreservePtrArith().

The PTRADD node and respective visitPTRADD() function were adapted by
@rgwott from the CHERI/Morello LLVM tree.
Original authors: @davidchisnall, @jrtc27, @arichardson.

The changes in this PR were extracted from PR #105669.
