[UBSan] Add returns-nonnull sanitizer.

Summary:
This patch adds a runtime check verifying that functions
annotated with "returns_nonnull" attribute do in fact return nonnull pointers.
It is based on suggestion by Jakub Jelinek:

tsan: allocate vector clocks using slab allocator
...
Vector clocks is the most actively allocated object in tsan runtime.
Current internal allocator is not scalable enough to handle allocation
of clocks in scalable way (too small caches). This changes transforms
clocks to 2-level array with 512-byte blocks. Since all blocks are of
the same size, it's possible to cache them more efficiently in per-thread caches.

This change introduces the first UBSan-specific runtime flag: print_stacktrace

in addition to diagnostic messages. For now these stacks are printed only
in vptr checker.

[UBSan] Introduce UBSAN_OPTIONS environment variable.

If UBSan is run in a standalone mode (w/o any other sanitizer), it
still uses functions from sanitizer_common, some of which depend on
the value of runtime flags. Allow to override the default values of these
flags with UBSAN_OPTIONS variable. In particular, UBSAN_OPTIONS=symbolize=0
can be used to turn off online symbolization.
