The code instrumented with ASan may have its own instance of the
...
mach_override library.
In this case chances are that functions from it will be called from
mach_override_ptr() during ASan initialization.
This may lead to crashes (if those functions are instrumented) or
incorrect behavior (if the implementations differ).
The attached patch renames mach_override_ptr() into
__asan_mach_override_ptr() and makes the rest of the mach_override
internals hidden.
The corresponding AddressSanitizer bug is

- Motivation is explained in the README, but basically it is convenient to be

so small, we can achieve this relatively easily by just stubbing out the
declarations of the external dependencies.
- This is in no way, shape, or form intended to be complete, it is just the
minimal stubs necessary to support the stuff we use.

lib: Add support for library wide utility functions, and make compilerrt_abort()

a real boy.
- The utility module needs to be included into every produced library, because
we don't have enough dependency tracking to know exactly which other modules
might require the utilities.
