[MSan] Add __msan_unpoison_string() to the public interface.

Using __msan_unpoison() on null-terminated strings is awkward because
strlen() can't be called on a poisoned string. This case warrants a special
interface function.

Reapply asan coverage changes 194702-194704.

I still don't know what is causing our bootstrapped LTO buildbots to fail,
but llvm r194701 seems to be OK and I can't imagine that these changes could
cause the problem.

...
Apple's bootstrapped LTO builds have been failing, and these changes (along
with llvm 194701) are the only things on the blamelist. I will either reapply
these changes or help debug the problem, depending on whether this fixes the
buildbots.

DataFlowSanitizer; compiler-rt changes.
...
DataFlowSanitizer is a generalised dynamic data flow analysis.
Unlike other Sanitizer tools, this tool is not designed to detect a
specific class of bugs on its own. Instead, it provides a generic
dynamic data flow analysis framework to be used by clients to help
detect application-specific issues within their own code.
