Ranger cache - always use range_from_dom when updating.
When updating an existing range, if we dont query the dom tree, we can
get the global range instead of a proper range on some incoming edges
which cause the range to not be refined properly.
PR tree-optimization/108356
gcc/
* gimple-range-cache.cc (ranger_cache::range_on_edge): Always
do a search of the DOM tree for a range.
gcc/testsuite/
* gcc.dg/pr108356.c: New.
