Use dominators to reduce cache-flling.
Before walking the CFG and filling all cache entries, check if the
same information is available in a dominator.
* gimple-range-cache.cc (ranger_cache::fill_block_cache): Check for
a range from dominators before filling the cache.
(ranger_cache::range_from_dom): New.
* gimple-range-cache.h (ranger_cache::range_from_dom): Add prototype.
