    ipa-sra: Disable candidates with no known callers (PR 110276)

    In IPA-SRA we use can_be_local_p () predicate rather than just plain
    local call graph flag in order to figure out whether the node is a
    part of an external API that we cannot change.  Although there are
    cases where this can allow more transformations, it also means we can
    analyze functions which have no callers at all, which is pointless.

    Moreover, it makes an assert of hint propagation trigger, which checks
    that we have looked at callers before processing hints that come from
    them.  This has been reported as PR 110276.

    This patch simply adds a check that a node has at least one caller
    into the early checks and makes the node a non-candidate for any
    transformation if it does not.
