Richard Smith c1d5471291 Make the big array in the UBSan C++ runtime be zero-initialized to dramatically
shrink the binary size of the ubsan runtime.

Also fix a bug where long-running processes could eventually trigger a crash in
the runtime by filling up the cache. I've not found a nice way to add a test for
this crasher; ideas welcome.
