Fix ranger when called from SCEV.

Do not pre-evaluate PHIs in the cache, and allow fill_block_cache to
be re-entrant.  This allows SCEV to call into ranger with a context
and not produce cycles or loops.

* gimple-range-cache.cc (ranger_cache::get_global_range): Do not
pre-evaluate PHI nodes from the cache.
(ranger_cache::fill_block_cache): Make re-entrant.
