    Guard function->cond_uids access [PR114601]

    PR114601 shows that it is possible to reach the condition_uid lookup
    without having also created the fn->cond_uids, through
    compiler-generated conditionals. Consider all lookups on non-existing
    maps misses, which they are from the perspective of the source code, to
    avoid the NULL access.
