gigi.h (gnat_init_decl_processing): Delete.

	* gcc-interface/gigi.h (gnat_init_decl_processing): Delete.
	* gcc-interface/decl.c (gnat_to_gnu_entity): Constify a few variables.
	<object>: Do not create the fake PARM_DECL if no debug info is needed.
	Do not create the corresponding VAR_DECL of a CONST_DECL for debugging
	purposes if no debug info is needed.
	Fix formatting.  Reorder and add comments.
	* gcc-interface/trans.c (gnat_to_gnu) <N_Attribute_Reference>: Constify
	variable and remove obsolete comment.
	* gcc-interface/utils.c (convert_vms_descriptor64): Tweak comment.
	(convert_vms_descriptor32): Likewise.
	(convert): Remove dead code.
	<UNCONSTRAINED_ARRAY_REF>: Pass the field instead of its name to build
	the reference to the P_ARRAY pointer.
	<POINTER_TYPE>: Likewise.
	(maybe_unconstrained_array) <UNCONSTRAINED_ARRAY_TYPE>: Likewise.
	(gnat_init_decl_processing): Delete, move contents to...
	* gcc-interface/misc.c (gnat_init): ...here.
