[PULL 3/6] linux-user: Use ARRAY_SIZE with bitmask_transtbl

Rather than using a zero tuple to end the table, use a macro to apply ARRAY_SIZE and pass that on to the convert functions. This fixes two bugs in which the conversion functions required that both the target and host masks be non-zero in order to continue, rather than require both target and host

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-
