Jakob Stoklund Olesen a2b7769a51 Revisit expanded instructions for legalization.
When an illegal instruction is replaced with other instructions, back up
and revisit the expanded instructions. The new instructions need to have
encodings assigned too.

This also allows for expansions to contain illegal instructions that
need to be legalized themselves.
