Similar to the MQPR register class as the MVE equivalent to QPR, this adds MQQPR and MQQQQPR register classes for the MVE equivalents of QQPR and QQQQPR registers. The MVE MQPR seemed have worked out quite well, and adding MQQPR and MQQQQPR allows us to a little more accurately specify the number of registers, calculating register pressure limits a little better.
