  Log Message:
  [DSE] Avoid calling isRemovable() on non-analyzable location (NFC)

At this point the instruction may either have an analyzable
write or be a terminator. For terminators, isRemovable() is not
necessarily well-defined. Move the check until after we have ensured
that it is not a terminator.
