* a-except.ads, a-except.adb: (Rmsg_28): Fix description for E.4(18)
check.
(Raise_Current_Excep): Call Debug_Raise_Exception just before
propagation starts, to let debuggers know about the event in a reliable
fashion.
(Local_Raise): Moved to System.Exceptions
More convenient to have this as a separate unit
* s-except.adb, s-except.ads: New files.
* a-exextr.adb (Unhandled_Exception): Delete - replaced by
Debug_Unhandled_Exception in System.Exceptions where it belongs
together with a couple of other debug helpers.
(Notify_Unhandled_Exception): Use Debug_Unhandled_Exception instead of
the former Unhandled_Exception.
* exp_ch11.ads, exp_ch11.adb: (Possible_Local_Raise): New procedure
(Warn_No_Exception_Propagation): New procedure
(Warn_If_No_Propagation): Rewritten for new warning generation
(Expand_Exception_Handlers): New warning generation
(Expand_N_Raise_xxx_Error): Rewritten for new warnings
(Add_Exception_Label): Use Special_Exception_Package_Used for test
instead of Most_Recent_Exception_Used (accomodates Exception_Traces)
(Expand_Local_Exception_Handlers): Unconditionally add extra block wrap
even if restriction is set (makes life easier in Check_Returns)
(Expand_Local_Exception_Handlers): Follow renamed entity chain when
checking exception identities.
(Expand_Local_Exception_Handlers): Do not optimize when all others case
(Expand_Local_Exception_Handlers): Set Exception_Junk flag on generated
block for handler (used by Check_Returns)
(Expand_Local_Exception_Handlers): Local_Raise now takes an address
(Expand_N_Handled_Sequence_Of_Statements): Properly handle -gnatd.x to
remove all exception handlers when optimizing local raise statements.
(Find_Local_Handler): Use Get_Renamed_Entity
(Expand_N_Handled_Sequence_Of_Statements): If the handled sequence is
marked analyzed after expanding exception handlers, do not generate
redundant cleanup actions, because they have been constructed already.
