When using a store_borrow for borrowed things, make sure to only store_borrow if we are using lowered addresses.

When opaque values are enabled, we do not need this store_borrow. This was
caught by the following tests:

  Swift(macosx-x86_64) :: SILGen/opaque_values_silgen.swift
  Swift(macosx-x86_64) :: SILGen/opaque_values_silgen_resilient.swift
