[msan] Chained origins re-design.
...
Generalize StackDepot and create a new specialized instance of it to
efficiently (i.e. without duplicating stack trace data) store the
origin history tree.
This reduces memory usage for chained origins roughly by an order of
magnitude.
Most importantly, this new design allows us to put two limits on
stored history data (exposed in MSAN_OPTIONS) that help avoid
exponential growth in used memory on certain workloads.
See comments in lib/msan/msan_origin.h for more details.

[CMake] Use ExternalProject to build MSan-ified version of libcxx for unit tests.
...
This change lets MSan rely on libcxx's own build system instead of manually
compiling its sources and setting up all the necessary compile flags. It would
also simplify compiling libcxx with another sanitizers (in particular, TSan).
The tricky part is to make sure libcxx is reconfigured/rebuilt when Clang or
MSan runtime library is changed. "clobber" step used in this patch works well
for me, but it's possible it would break for other configurations - will
watch the buildbots.

[msan] Fix invalid origin copying.
...
Origin copying may destroy valid origin info. This is caused by
__msan_copy_origin widening the address range to the nearest 4-byte aligned
addresses both on the left and on the right. If the target buffer is
uninitialized and the source is fully initialized, this will result in
overriding valid origin of target buffer with stale (possibly 0) origin of the
source buffer.
With this change the widened origin is copied only if corresponding shadow
values are non zero.

This reverts commit r187788.
The test case is unreliable (as the test may be run in a situation in
which it has no affinity with cpu0). This can be recommitted with a more
reliable test - possibly using CPU_COUNT != 0 instead (I wasn't entirely
sure that a process was guaranteed to have at least one affinity, though
it seems reasonable, or I'd have made the change myself).
