This function is called once (source level) compilation unit is finalized
and it will no longer change.
In the unit-at-a-time the call-graph construction and local function
analysis takes place here. Bodies of unreachable functions are released
to conserve memory usage.
??? The compilation unit in this point of view should be compilation
unit as defined by the language - for instance C frontend allows multiple
compilation units to be parsed at once and it should call function each
time parsing is done so we save memory.
The function can be called multiple times when multiple source level
compilation units are combined (such as in C frontend)

When function or variable is referenced by some hidden way the call-graph

There should be little need to call this function and all the references
should be made explicit to cgraph code. At present these functions are
used by C++ frotend to explicitely mark the keyed methods.
