* gcc-interface/gigi.h (gnat_stabilize_reference): Adjust prototype.
* gcc-interface/decl.c (gnat_to_gnu_entity): Do not rely on const_flag
to detect constant renamings. Be prepared for specific pattern of
renamed object based on function calls. Create a constant object
for the renaming of a NULL_EXPR or of a CONSTRUCTOR. Adjust calls
to gnat_stabilize_reference and tidy up. Remove redundant tests.
(elaborate_expression_1): Remove obsolete test and tidy up.
* gcc-interface/trans.c (Call_to_gnu): Do not stabilize In/Out or Out
parameters passed by reference.
(gnat_to_gnu) <N_Selected_Component>: Remove redundant protection again
side-effects.
Use gnat_protect_expr instead of gnat_stabilize_reference for general
protection against side-effects.
* gcc-interface/utils2.c (gnat_stable_expr_p): New predicate.
(gnat_save_expr): Invoke it.
(gnat_protect_expr): Likewise.
(gnat_stabilize_reference_1): Likewise. Remove useless propagation
of TREE_THIS_NOTRAP.
(gnat_stabilize_reference): Remove parameter and adjust throughout.
Delete ADDR_EXDR, COMPOUND_EXPR and CONSTRUCTOR cases.
Restrict CALL_EXPR case to atomic loads and tweak ERROR_MARK case.
