Evgeniy Stepanov 9a4d6586b4 [msan] Handle mixed track-origins and keep-going settings (llvm part). ...

Before this change, each module defined a weak_odr global __msan_track_origins 
with a value of 1 if origin tracking is enabled, 0 if disabled. If there are 
modules with different values, any of them may win. If 0 wins, and there is at 
least one module with 1, the program will most likely crash.

With this change, __msan_track_origins is only emitted if origin tracking is 
on. Then runtime library detects if there is at least one module with origin 
tracking, and enables runtime support for it.
