    INSERT/EXTRACT_VECTOR_ELT with non-constant element.
    More patterns and tests added.

Waiting with VLLEZ, VLEH, ... patterns:  Splitting "everything" for now. In some test cases this could be improved, e.g. with a vector in a register, a VLEH and then VST, which could actually be done. Maybe that can wait as long as it is functional...

Found a derived test case with an IR that seems legal, but fails in compilation - will investigate it next.
