Only the error cases of overwriting readonly properties need the
language_mode to decide whether to throw or be silent. Reading it
from the feedback vector's metadata (just like the C++ code in
ic.cc does) removes the need to duplicate each stub for each
language_mode ("StoreIC" + "StoreICStrict" etc.).
