No tags for projections in record pattern synonyms

[andreasabel]

E.g. this definition:

{-# LANGUAGE PatternSynonyms #-}

pattern MyJust :: a -> Maybe a
pattern MyJust { theThing } = Just theThing

just produces (with ghc-tags Foo.hs -c) a tag for the MyJust synonym, but not the theThing field:

...
!_TAG_KIND_DESCRIPTION!Haskell	p	/pattern synonym/
...
MyJust	RecordPatternSynonym.hs	4;"	p

NB. Noticed this first for my own tool:
