Add and propagate template phase for constants. (#4964)

Browse Source 
Treat template bindings as introducing template phase, and propagate it
in the same way we propagate the checked generic phase.

Rename "symbolic" to "checked symbolic" to make room for "template
symbolic". Also rename "phase" to "dependence".
