For all RUN lines starting with "not", redirect stderr to /dev/null so tests don't fail when (expected) error output is produced. This fixes 17 tests. While I was there, I also made all RUN lines of the form "not llvm-as..." a bit more consistent, they now all redirect stderr and stdout to /dev/null and use input redirect to read their input. llvm-svn: 52174

Fix for PR1633: Verifier doesn't fully verify GC intrinsics LLVM now enforces the following prototypes for the write barriers: <ty>* @llvm.gcread(<ty2>*, <ty>**) void @llvm.gcwrite(<ty>*, <ty2>*, <ty>**) And for @llvm.gcroot, the first stack slot is verified to be an alloca or a bitcast of an alloca. Fixes test/CodeGen/Generic/GC/lower_gcroot.ll, which violated these. llvm-svn: 42051
