This fixes bootstrap of GCC with BOOT_CFLAGS="-g -O2 -fgraphite-identity -floop-nest-optimize -floop-block -floop-interchange -floop-strip-mine". It passes regstrap on amd64-linux. A previous change (https://gcc.gnu.org/viewcvs/gcc?view=revision&revision=213816), replaced isl_int with isl_val because isl_int would be deprecated. Since isl_val has stricter checks, it exposed the bug. In the test case (isl_set_max_val) would return infinity which would remain unchecked. We now check if the value returned is an integer or not, and bail out if it isn't. The other problem was that we were allowing all kinds of data-refs in a scop. Now we discard a scop if it has any date-ref other than (ARRAY_REF, MEM_REF, COMPONENT_REF).

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.
