[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.
