      Respect SPECIALISE pragmas in instance decls
	-------------------------------------

For some time now we have simply been discarding SPECIALISE pragmas
in instance declarations.  I think this was my fault, at some point
when I was re-plumbing TcClassDcl.lhs, but it's been this way for
some time.

The only uses of this facility in the Prelude are in GHC/Float.lhs
and GHC/Real.lhs, which affected the efficiency of the Float and
Double instance of properFraction, floor, ceiling, etc.

Ah well, it's fixed now.
