Jan Hubicka 6a64964212 Avoid redundant entries in modref access lists.
In PR101296 Richard noticed that modref is giving up on analysis in milc by
hitting --param=modref-max-accesses limit.  While cleaning up original modref
patch I removed code that tried to do smart things while merging accesses
because it had bugs and wanted to reimplement it later which I later forgot.

This patch adds logic that avoids adding access and its subaccess to the list
which is just waste of memory and compile time.  Incrementally I will add logic
merging the ranges.

README

This directory contains the GNU Compiler Collection (GCC).

The GNU Compiler Collection is free software.  See the files whose
names start with COPYING for copying permission.  The manuals, and
some of the runtime libraries, are under different terms; see the
individual source files for details.

The directory INSTALL contains copies of the installation information
as HTML and plain text.  The source of this information is
gcc/doc/install.texi.  The installation information includes details
of what is included in the GCC sources and what files GCC installs.

See the file gcc/doc/gcc.texi (together with other files that it
includes) for usage and porting information.  An online readable
version of the manual is in the files gcc/doc/gcc.info*.

See http://gcc.gnu.org/bugs/ for how to report bugs usefully.

Copyright years on GCC source files may be listed using range
notation, e.g., 1987-2012, indicating that every year in the range,
inclusive, is a copyrightable year that could otherwise be listed
individually.
