    sra: Fix the fix for PR 102505 (PR 102886)

    I was not careful with the fix for PR 102505 and did not craft the
    check to satisfy the verifier carefully, which lead to PR 102886.
    (The verifier has the test structured differently and somewhat
    redundantly, so I could not just copy it).

    This patch fixes it.  I hope it is quite obvious correction of an
    oversight and so will commit it if survives bootstrap and testing on
    x86_64-linux and ppc64le-linux.

    Testcase for this bug is gcc.dg/tree-ssa/sra-18.c (but only on
    platforms with constant pools).  I will backport the two fixes
    to the release branches squashed.
