    Darwin, PCH: Rework hooks for relocatable implementation [PR71934].

    Now we have a relocatable PCH implementation we can revise the
    hooks that find and use the mmapped memory.  Specifically, this
    removes the extra checking and diagnostic output for cases that
    were likely to fail in a non-relocatable scenario.
