[COMMITTED] Grow non_null_ref bitmap when num_ssa_names increases.
Commit Message
The strlen pass changes the IL as it works with the ranger. This
causes the non_null_ref code to sometimes get asked questions about new
SSA names.
Tested on x86-64 Linux.
gcc/ChangeLog:
* gimple-range-cache.cc (non_null_ref::non_null_deref_p): Grow
bitmap if needed.
