Silence static analyzer warnings about memory leaks

The static analyzer complains that this memory is leaked regardless of
how I try to work around it (unless we escape the memory by using a
global or something, but...). Basically, as long as there's some sort
of operation on the reinterpret_cast'ed pointer, it complains. If we
remove the bitwise negations, it doesn't. Doing so would presumably
defeat the purpose of this test, though, so add a NOLINT.

Bug: 27101951
Test: mma. No more static analyzer warning for this file.
