Evgeniy Stepanov 04b7bff1fe [sanitizer] Intercept sched_getaffinity. 
Re-applying with a more reliable test case.

David Blaikie 787e2b6499 Revert "[sanitizer] Intercept sched_getaffinity." 
This reverts commit r187788.

The test case is unreliable (as the test may be run in a situation in
which it has no affinity with cpu0). This can be recommitted with a more
reliable test - possibly using CPU_COUNT != 0 instead (I wasn't entirely
sure that a process was guaranteed to have at least one affinity, though
it seems reasonable, or I'd have made the change myself).

Chandler Carruth 2b3c00eec7 Revert r179012: "[msan] Intercept glob()." 
This was committed without tests and contains obvious bugs. That's not
acceptable. It broke address sanitizer for most programs using glob(3).
