Add -f[no-]strict-overflow to the Clang driver. Use it to set the default for -fwrapv if that flag isn't specified explicitly. We always prefer an explict setting of -fwrapv when present. Also adds support for -fno-wrapv to allow disabling -fwrapv even when -fno-strict-overflow is passed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@128353 91177308-0d34-0410-b5e6-96231b3b80d8
