Ignore Tickish Breakpoints when serialising Core into interface files

This fixes Trac #8333

Thanks to 'klao', who identified the cause and provided the patch

Kill Type.isKindTy in favour of Kind.isKind (same code)
Nuke tc-trace that makes the typechecker loop

careful knot-tying
Improve error message for deriving polykinded Typeable (Trac #7800)

Thanks to Krzysztof Gogolewski (monoidal) for the first draft of this patch
