We copied the data from the general register input to the
vector register output, but have not yet replicated it.
We intended to fall through into the vector-vector case,
but failed to redirect the input register.

This is caught by an assertion failure in tcg_out_insn_VRIc,
which diagnosed the incorrect register class.
