Rakudo build broken as of parrot RELEASE_2_10_1-633-ga3ca6c8

[Andrew Whitworth]

We do have this feature. There is a function Parrot_warn_deprecated
that we call and will print out warnings if you're using a deprecated
feature. There are performance implications for this, especially if we
are calling a deprecated function many times (only in debug mode, I
think), and not all renameable functions use this because it would
basically have to go everywhere. For something like TT #443 this is
way overkill, but the idea exists and is used in other deprecations.
