Measure typeclass scaling using new scheme
Measure typeclass scaling using new scheme

Summary:

 - Code size increases by 13% (counting characters) to 15% (counting words)
 - Compile time increases by 3% (wallclock) to 4% (user)

Runtime should be somewhat better for new scheme since there are fewer allocations.

(Btw, the -Yshow-no-inlines option in the old measurements should be ignored; it is
no linger valid and was not included in the tests)
