[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 git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@334433 91177308-0d34-0410-b5e6-96231b3b80d8

-// With allocator_may_return_null=1 the allocator should return 0, except the
-// operator new(), which should crash anyway (operator new(std::nothrow) should
-// return nullptr, indeed).
