* trans.c (call_to_gnu) <TYPE_RETURNS_BY_TARGET_PTR_P>: Return an
expression with a COMPOUND_EXPR including the call instead of emitting
the call directly here.
(gnat_to_gnu) <N_Slice>: Do not return a non-constant low bound if the
high bound is constant and the slice is empty. Tidy.
(tree_transform, case N_Op_Not): Handle properly the case where the
operation applies to a private type whose full view is a modular type.
(Case_Statement_To_gnu): If an alternative is an E_Constant with an
Address_Clause, use the associated Expression as the GNAT tree
representing the choice value to ensure the corresponding GCC tree is
of the proper kind.
(maybe_stabilize_reference): Stabilize COMPOUND_EXPRs as a whole
instead of just the operands, as the base GCC stabilize_reference does.
<CALL_EXPR>: New case. Directly stabilize the call if an lvalue is not
requested; otherwise fail.
(addressable_p) <COMPONENT_REF>: Do not test DECL_NONADDRESSABLE_P.
