    [Committed] PR other/106575: Use "signed char" in new fold-eqandshift-4.c

    My recently added testcase gcc.dg/fold-eqandshift-4.c, incorrectly assumed
    that "char" was "signed char", and hence fails on powerpc64 where this
    isn't the case.  Fixed by making "signed char" explicit where needed in
    this test.  Committed as obvious.
