Fix PR rtl-optimization/108274

Unlike other IPA passes, the ICF pass can be run at -O0 and some testcases
rely on this in the testsuite.  Now it effectively creates a tail call so
the DF information needs be updated in this case after epilogue creation.

* function.cc (thread_prologue_and_epilogue_insns): Also update the
DF information for calls in a few more cases.
