ubsan: When diagnosing something wrong somewhere in memory, emit a note
...
pointing at the bad location and a snippet of nearby memory values. This is
strictly best-effort; reading these bytes to display the note could lead to a
seg fault, and that's explicitly OK.

one out from the return address. Currently, we can only resolve this address to
a file and line number if we have an external symbolizer.

Fix the bootstrap of CompilerRT with host compilers that don't support

emulating 128-bit arithmetic on 32-bit x86 targets. This should get the
bootstrap back for GCC 4.6 at least.
Suggestions on better ways to do the detection here are welcome...
