or1k: Add the l.muld, l.muldu, l.macu, l.msbu insns

Also fix the incorrect definitions of multiply and divide carry and
overflow float.

Changes to the instructions are made in the .cpu file, then we
regenerate the binutils and sim files.

The changes also required a few fixups for tests and additional sim helpers.
