* Avoid nasty name clash with associated data types (fixes Trac #2888)
The main bug was in TcHsType; see Note [Avoid name clashes for
associated data types]. However I did a bit of re-factoring while
I was abouut it.
I'm still a but unhappy with the use of TyCon.setTyConArgPoss; it'd
be better to construct the TyCon correctly in the first place. But
that means passing an extra parameter to tcTyDecl1... maybe we should
do this.
