In GHC 7.10.1, Template Haskell support was added for all calling conventions. Unfortunately a few cases are unhandled, which makes the TH code treat the prim and javascript calling conventions as if they were C calling conventions, adding the static keyword and running them through parseCImport.

This is particularly bad for javascript imports, since most JS imports aren't valid C imports, so they get rejected.

I'm testing a fix for this that I'll submit later today. I hope this is in time for 7.10.2
