Duncan P. N. Exon Smith da91cbdfa8 InstrProf: lit.cfg magic for running tests from source 
Implement magic in compiler-rt to enable llvm-lit to be invoked on the
source tree in lib/profile.  This relies on a paired commit in the llvm
tree that exposes a new built-in parameter.

Add the test infrastructure for testing lib/profile and a single test.
This initial commit only enables the tests on Darwin, but they'll be
enabled on Linux soon after.

Sergey Matveev fa76f3b3a5 [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.
