Disable folding in genCreateAddrMode under LB-specific circumstances.

If we are calling this function during emit with `fold = true`, then disable
folding iff the value to be used as the index is already in a register.
Not doing so can cause entire address modes to be folded away, which
leads to asserts and potential SBCG.

Fixes VSO 468730.
