* decl.c (compatible_signatures_p): New function. The intended purpose
is to check if two function signatures for a call-site and a callee are
compatible enough for the call to be valid. The underlying purpose is
to check if a call to a mapped builtin is using the right interface.
The current code actually does not check antyhing - this a placeholder
for future refinements.
(gnat_to_gnu_entity) <E_Subprogram_Call>: Add preliminary bits to handle
builtin calls for convention Intrinsic.
* gigi.h (builtin_decl_for): Declare (new function).
* utils.c (gnat_install_builtins): Install the target specific builtins.
(builtin_decl_for): New function, provide a dummy body for now.
