Summary:
Operator new interceptors behavior is now controlled by their nothrow
property as well as by allocator_may_return_null flag value:
- allocator_may_return_null=* + new() - die on allocation error
- allocator_may_return_null=0 + new(nothrow) - die on allocation error
- allocator_may_return_null=1 + new(nothrow) - return null
Ideally new() should throw std::bad_alloc exception, but that is not
trivial to achieve, hence TODO.

We already have %env_asan_opts for ASan, let's implement the same for TSan.
