Yeah this is a weird API I almost thought to make it a protected method because
the only user should be SBFrame where we need to distinguish between the
"currently in-effect high memory mask" and "the current Process mask setting,
which may be unset". For the effective high memory mask, if the user hasn't
specified a high memory addressable bits setting, and the process doesn't have
a mask set, then we are in a "one-mask-for-all-addresses" mode and we return
the low memory address mask.
