Revert "Add built-in functions as a Transform pass."
This reverts commit 7d62da53c9408208ce53d2f363dc2a59990d16e0.
Reason for revert: breaking Graphite (referencing global variable `$Precision`)
Original change's description:
> Add built-in functions as a Transform pass.
>
> Previously, each FunctionDefinition contained a set which tracked all
> of the built-in functions that it called--kind of like ProgramUsage,
> on a function-by-function basis. This map was used to populate built-
> in functions into the program.
>
> The map has been removed and now we scan usage.fCallCounts directly to
> find and include calls into built-in functions. We continue scanning
> and adding until we reach steady-state. We don't need to run a
> ProgramVisitor over the code at all, or maintain any state in the
> FunctionDefinition.
