Log:
Fix PR49471: canonicalize_loop_ivs should not generate unsigned types.

2011-07-27  Sebastian Pop  <sebastian.pop@amd.com>

    PR tree-optimization/49471
    * tree-ssa-loop-manip.c (canonicalize_loop_ivs): Build an unsigned
    iv only when the largest type is unsigned.  Do not call
    lang_hooks.types.type_for_size.

    * testsuite/libgomp.graphite/force-parallel-1.c: Un-xfail.
    * testsuite/libgomp.graphite/force-parallel-2.c: Adjust pattern.
