Summary: Keeping msan a function pass requires replacing the module level initialization: That means, don't define a ctor function which calls __msan_init, instead just declare the init function at the first access, and add that to the global ctors list. Changes: - Pull the actual sanitizer and the wrapper pass apart. - Add a newpm msan pass. The function pass inserts calls to runtime library functions, for which it inserts declarations as necessary. - Update tests. Caveats: - There is one test that I dropped, because it specifically tested the definition of the ctor.
