Keith Randall 2fe4b14795 [dev.typeparams] cmd/compile: ensure methods of generic types survive linker pruning 
Calling MarkTypeUsedInInterface before inlining is problematic (when
using the containing function as the reference source), because we end
up attaching a relocation to the original function, which is then
deadcode removed because all instances of it were inlined. (All other
current uses of MarkTypeUsedInInterface happen after inlining, so they
don't have this problem.)

Instead, attach the relocation to the dictionary in which the type
appears.  This should always work, because if the dictionary is ever
deadcode eliminated, then the type can never be put in an interface,
which means we indeed don't need its methods.

This CL is a bit overkill, as not *all* types in the dictionary need
this mark, but it is sufficient for now.
