Add dg-line

Context: there are currently two types of line number supported in
dg-{error,warning,message,bogus} directives: absolute and relative.  With an
absolute line number, it's immediately clear what line number is meant, but
when a line is added at the start of the file, the line number needs to be
updated.  With a relative line number, that problem is solved, but when relative
line numbers become large, it becomes less clear what line it refers to, and
when adding a line inbetween the directive using the relative line number and
the line it refers to, the relative line number still needs to be updated.

Add a directive dg-line with argument varname, that saves the line number

should), the pragma has no effect. If the procedure does return,

* exp_ch6.adb (Expand_Actuals): This is the
root of the problem. It took N as an 'in out' parameter, and in
some cases, rewrote N, but then set N to Original_Node(N). So
the node returned in N had no Parent. The caller continued
processing of this orphaned node. In some cases that caused a
crash (e.g. Remove_Side_Effects climbs up Parents in a loop,
and trips over the Empty Parent). The solution is to make N an
'in' parameter.  Instead of rewriting it, return the list of
post-call actions, so the caller can do the rewriting later,
after N has been fully processed.
(Expand_Call_Helper): Move most of Expand_Call here. It has
too many premature 'return' statements, and we want to do the
rewriting on return.
(Insert_Post_Call_Actions): New procedure to insert the post-call
actions in the appropriate place. In the problematic case,
that involves rewriting N as an Expression_With_Actions.
(Expand_Call): Call the new procedures Expand_Call_Helper and
Insert_Post_Call_Actions.

* sem_ch8.adb (Use_One_Type): If a use_type_clause
is redundant, set its Used_Operations to empty. This is only
necessary for use clauses that appear in the parent of a generic
child unit, because those use clauses get reanalyzed when we
instantiate the generic, and we don't want the Used_Operations
carried over from the original context (where it was probably
not redundant).
