Rewrite some tests with FileCHeck in X86 codegen - Revise previous patches of the same purpose by fixing *) grep <PA> | not grep <PB> semantically is not the same as CHECK: <PA>{{^<PB>.*$}} as the former will check all occurrences of <PA> while the later only check the first match. As the result, CHECK needs putting in all place where <PA> occurs. *) grep <PA> | count <N> needs a final CHECK-NOT of the same pattern. (As 'CHECK-<N>' is proposed for discussion, converting 'grep | count <N>' where N > 1 is postponed.) llvm-svn: 180742
