3df53e5554c86bfbf7f7dbfd3052678eb03afcdb range-cache: Fix ICE on SSA_NAME with def_stmt not yet in the IL [PR116898]
Some passes like the bitint lowering queue some statements on edges and only
commit them at the end of the pass. If they use ranger at the same time,
the ranger might see such SSA_NAMEs and ICE on those. The following patch
instead just punts on them.

* gimple-range-cache.cc (ranger_cache::block_range): If a SSA_NAME
with NULL def_bb isn't SSA_NAME_IS_DEFAULT_DEF, return false instead
of failing assertion. Formatting fix.
* gcc.dg/bitint-110.c: New test.
