This patch evolves the cache of `ControlFlowContext`s into a parameter that the
user can supply. Specifically, the system now limits inline analysis of function
calls specifically to those functions contained in a user-supplied map from
"fully qualified name" to `ControlFlowContext`.

To avoid the cost of generating the fully qualified function name for every
`CallExpr`, we cache the results of the map lookup in an intermediary map over
`FunctionDecl*`s.
