An address containing an object header is sometimes interpreted as a object slot due to array truncation and concurrent marking/sweeping. Always accessing it as a word assuages TSAN that it won't be subject to tearing, and allows for the removal of TSAN suppressions from header access. In turn, this will allow TSAN to verify some acquire/release header accesses.
