Remove some horrible munging of origins for Coercible
I just didn't think it was buying enough for all the cruft it caused.
We can put some back if people start complaining about poor error
messages. I forget quite how I tripped over this but I got sucked in.
* Lots of tidying up in TcErrors
* Rename pprArisingAt to pprCtLoc, by analogy with pprCtOrigin
* Remove CoercibleOrigin data constructor from CtOrigin
* Make relevantBindings return a Ct with a zonked
and tidied CtOrigin
* Add to TcRnTypes
ctOrigin :: Ct -> CtOrigin
ctEvOrigin :: CtEvidence -> CtOrigin
setCtLoc :: Ct -> CtLoc -> Ct
