Don't save ssa-name pointer in dependency cache.
If the direct dependence fields point directly to an ssa-name,
its possible that an optimization frees an ssa-name, and the value
pointed to may now be in the free list. Simply maintain the ssa
version number instead.
PR tree-optimization/109417
* gimple-range-gori.cc (range_def_chain::register_dependency):
Save the ssa version number, not the pointer.
(gori_compute::may_recompute_p): No need to check if a dependency
is in the free list.
* gimple-range-gori.h (class range_def_chain): Change ssa1 and ssa2
fields to be unsigned int instead of trees.
(ange_def_chain::depend1): Adjust.
(ange_def_chain::depend2): Adjust.
* gimple-range.h: Include "ssa.h" to inline ssa_name().
