    ipa: Do not emit info about temporary clones to ipa-clones dump (PR119852)

    As described in PR 119852, the output of -fdump-ipa-clones can contain
    "(null)" as the suffix/reason for cloning when we need to create a
    clone to hold the original function during recursive inlining.  Such
    clone is never output and so should not be part of the dump output
    either.
