Eric Fiselier 909deebfc8 [compiler-rt] Make the MSAN wmemset intercepter call wmemset instead of memset. Fixes PR 21579 
Summary:
Exactly what the title says. I've tested this change against the libc++ test failures and it solves all of them. The check-msan rule also still passes.
I'm not sure why it called memset originally. 

I can add tests if requested but currently there are no tests involving wide chars and they are a c++11 features.

Evgeniy Stepanov 7555f5ed1f [msan] Remove MSanDR and supporting code. 
MSanDR is a dynamic instrumentation tool that can instrument the code
(prebuilt libraries and such) that could not be instrumented at compile time.

This code is unused (to the best of our knowledge) and unmaintained, and
starting to bit-rot.

Alexey Samsonov 91bb8e0e3a Generalize sanitizer allocator public interface. 
Introduce new public header <sanitizer/allocator_interface.h> and a set
of functions __sanitizer_get_ownership(), __sanitizer_malloc_hook() etc.
that will eventually replace their tool-specific equivalents
(__asan_get_ownership(), __msan_get_ownership() etc.). Tool-specific
functions are now deprecated and implemented as stubs redirecting
to __sanitizer_ versions (which are implemented differently in each tool).

Replace all uses of __xsan_ versions with __sanitizer_ versions in unit
and lit tests.

Evgeniy Stepanov 208aae8ee0 [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.
