<p>
Here we create a map that uses {@link TaintTraceSpace}s. The framework provides the concept
of a space map where storage is actually a cache backed by some other object. The backing
object we'll use here is {@link TracePropertyMapSpace}, which is provided by the
TraceModeling module. We'll need a little bit of extra logic for fetching a register space
vs. a plain memory space, but after that, we need not care which address space the backing
object is for.
