Support all of the easy GM block sizes. Use direct memory operations, since the pointers are aligned. While BS=2 (16 bytes, 1 tag) is a legal setting, that requires an atomic store of one nibble. This is not difficult, but there is also no point in supporting it until required. Note that cortex-a710 sets GM blocksize to match its cacheline size of 64 bytes. I expect many implementations will also match the cacheline, which makes 16 bytes very unlikely.
