LOG: [Index] Migrate away from PointerUnion::dyn_cast (NFC) (#124389)

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>

Literal migration would result in dyn_cast_if_present (see the
definition of PointerUnion::dyn_cast), but this patch uses dyn_cast
because we expect DclInfo.DeclOrMacro to be nonnull.

Added: 
    

Modified: 
    clang/lib/Index/FileIndexRecord.cpp

Removed:
