[Sanitizers] Move allocator_returns_null.cc test to common.
Summary: Add allocator_returns_null.cc test to sanitizer_common and remove all sanitizer-specific ones except: - HWASan is not covered by sanitizer_common - TSan allocator does not have comprehensive error reporting yet Reviewers: vitalybuka Subscribers: kubamracek, delcypher, #sanitizers, llvm-commits Differential Revision: https://reviews.llvm.org/D47971 llvm-svn: 334433
