  -----------
  [lld] Migrate away from PointerUnion::dyn_cast (NFC) (#124504)

Note that PointerUnion::dyn_cast has 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>

This patch migrates uses of PointerUnion::dyn_cast to
dyn_cast_if_present (see the definition of PointerUnion::dyn_cast).
Note that we cannot use dyn_cast in any of the migrations in this
patch; placing

  assert(!X.isNull());

just before any of dyn_cast_if_present in this patch triggers some
failure in check-lld.
