* gcc-interface/utils2.c (build_call_alloc_dealloc_proc): New
helper for build_call_alloc_dealloc with arguments to be interpreted
identically. Process the case where a GNAT_PROC to call is provided.
(maybe_wrap_malloc): New helper for build_call_alloc_dealloc, to build
and return an allocator for DATA_SIZE bytes aimed at containing a
DATA_TYPE object, using the default __gnat_malloc allocator. Honor
DATA_TYPE alignments greater than what the latter offers.

release a DATA_TYPE object designated by DATA_PTR using the
__gnat_free entry point.
(build_call_alloc_dealloc): Expect object data type instead of naked
alignment constraint. Use the new helpers.
(build_allocator): Remove special processing for the super-aligned
case, now handled by build_call_alloc_dealloc. Pass data type instead
of the former alignment argument, as expected by the new interface.
