Refactor graphite-isl-ast-to-gimple.c:
Refactor so that each function can access 'region'. This will help
maintain a parameter rename_map within a region. No functional change intended.
This patch will be followed by another set of patches
where translate_isl_ast_to_gimple::region is used to keep parameters which need
renaming. Since we are planning to remove limit_scops, we now have to maintain a
set of parameters which needs renaming. This refactoring helps avoid passing
`region' to all the functions in this file.
It passes bootstrap and regtest.

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).
