[PATCH] The msan interface stubs for non-instrumented code were missing a bunch of entry points.

[Chandler Carruth]

Hi eugenis,

The msan interface stubs for non-instrumented code were missing a bunch of entry points. I'm not really sure this is the right pattern, but there is no reason to be inconsistent. If we're providing the interface stubs when not instrumenting code with msan we should provide all of them rather than a subset.

I'm not aware of any testing for this code path, but if you guys can point me at testing for it I'll happily add some tests.
