* sem.util.ads, sem_util.adb (Denotes_Same_Object,
Denotes_Same_Prefix): New functions to detect overlap between actuals
that are not by-copy in a call, when one of them is in-out.
* sem_warn.ads, sem_warn.adb (Warn_On_Overlapping_Actuals): New
procedure, called on a subprogram call to warn when an in-out actual
that is not by-copy overlaps with another actual, thus leadind to
potentially dangerous aliasing in the body of the called subprogram.
Currently the warning is under control of the -gnatX switch.
* sem_res.adb (resolve_call): call Warn_On_Overlapping_Actuals.

see if the integer promotion is possible; in such case the runtime
checks are not generated.
