    ipa-sra: Check also ECF_LOOPING_CONST_OR_PURE when evaluating calls

    in PR 103267 Honza found out that IPA-SRA does not look at
    ECF_LOOPING_CONST_OR_PURE when evaluating if a call can have side
    effects.  Fixed with this patch.  The testcase infinitely loops in a
    const function, so it would not make a good addition to the testsuite.

    This patch is a manual backport of commit
    e5440bc08e07fd491dcccd47e1b86a5985ee117c to the old "early" IPA-SRA.
