Our template emission strategy is broken

Once that is done and we have a clearer understanding of what the 
problems are, we could rediscuss the emission rules.

Ultimatively the decision to instantiate/emit as few templates as 
possible sped up compilation a lot but basically means -c with 
multiple objects will never work reliably.
Compiling separate objects is a C++-idiom anyhow and doesn't make 
too much sense for D. Instead separating your codebase into 
packages with little interdependencies and always recompiling 
those packages when something changes should be the preferred way.
