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.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180742 91177308-0d34-0410-b5e6-96231b3b80d8 2013-04-29 22:41:29 +00:00			`; RUN: llc < %s -march=x86-64 \| FileCheck %s`
