[dev.typeparams] cmd/compile: add stenciling of simple generic functions

Browse source 
Allow full compilation and running of simple programs with generic
functions by stenciling on the fly the needed generic functions. Deal
with some simple derived types based on type params.

Include a few new typeparam tests min.go and add.go which involve
fully compiling and running simple generic code.
