Fix exact printing of the HsRule namewip/romes/ttg-prune
Prior to this branch, the HsRule name was
XRec pass (SourceText,RuleName)
and there is an ExactPrint instance for (SourceText, RuleName).
The SourceText has moved to a different location, so synthesise the
original to trigger the correct instance when printing.
We need both the SourceText and RuleName when exact printing, as it is
possible to have a NoSourceText variant, in which case we fall back to
the FastString.
