2f8238f8 - [llvm] Migrate away from PointerUnion::{is,get} (NFC) (#119679)

[llvm] Migrate away from PointerUnion::{is,get} (NFC) (#119679) Note that PointerUnion::{is,get} have been soft deprecated in PointerUnion.h: // FIXME: Replace the uses of is(), get() and dyn_cast() with // isa<T>, cast<T> and the llvm::dyn_cast<T> I'm not touching PointerUnion::dyn_cast for now because it's a bit complicated; we could blindly migrate it to dyn_cast_if_present, but we should probably use dyn_cast when the operand is known to be non-null.
