documentation: Record limitations of bitfields and small variables This commit documents the fact that it is not safe to use bitfields as shared variables in synchronization algorithms. It also documents that CPUs must be able to concurrently load from and store to adjacent one-byte and two-byte variables, which is in fact required by the C11 standard (Section 3.14).
