Herald added a subscriber: sdardis.

Rebased to work with TOT.
Removed microMIPS32r6 implementation of LH and LHU instructions because it is not required.
Added required DAG patterns for microMIPS LH and LHU instructions so they can be selected properly.
Expanded .ll test with load atomic to check added DAG pattern.
Tests for the standard encodings are sorted in alphabetical order.
Added invalid tests for the negative ranges.
