Do not pass NULL to memset in ssa_global_cache.
The code computing ranges in PHIs in the path solver reuses the
temporary ssa_global_cache by calling its clear method. Calling it on
an empty cache causes us to call memset with NULL.
Tested on x86-64 Linux.
gcc/ChangeLog:
PR tree-optimization/103229
* gimple-range-cache.cc (ssa_global_cache::clear): Do not pass
null value to memset.
