Sergey Matveev fd10073aeb [lsan] When detect_leaks=false, be completely silent. 
In particular, don't make a fuss if we're passed a malformed suppressions file,
or if we have trouble identifying ld.so. Also, make LSan interface functions
no-ops in this case.

Peter Collingbourne b745eec4e4 Use internal_memset to initialize this variable. 
Otherwise, the compiler may use memset in non-optimized builds, which is
forbidden in the nolibc part of the runtime.

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.
