[Ada] Crash on entry call with preconditions and access parameters

Authentication-results: sourceware.org; auth=none

When an entry has preconditions, the entry call is wrapped in a procedure call
that incorporates the precondition checks. To prevent a double expansion, with
possible duplication of extra formals, that procedure call must only be pre-
nalyzed and resolved. Expansion takes place upon return to the caller
Resolve_Call.

No short example available.

Tested on x86_64-pc-linux-gnu, committed on trunk

	* sem_res.adb (Resolve_Entry_Call): When an entry has
	preconditions, the entry call is wrapped in a procedure call
	that incorporates the precondition checks. To prevent a double
	expansion, with possible duplication of extra formals, that
	procedure call must only be pre-analyzed and resolved. Expansion
	takes place upon return to the caller Resolve_Call.
