[Rust] Should LowLevelIL{Instruction,Expression} be Copy (or at least Clone)? #6885
Description
It is currently not possible to copy or clone a LowLevelILInstruction or LowLevelILExpression. This can complicate working with them in some circumstances. The medium- and high-level equivalents are Clone.
Given they're a small struct holding only a reference to their containing LowLevelILFunction plus their instruction / expression index, copying is cheap enough that I could see these being Copy. The medium- / high-level equivalents are larger and so make sense as Clone.
