Add a warning to diagnose statements in C++ like "*(volatile int*)x;". Conceptually, this is part of -Wunused-value, but I added a separate flag -Wunused-volatile-lvalue so it doesn't get turned off by accident with -Wno-unused-value. I also made a few minor improvements to existing unused value warnings in the process. <rdar://problem/11516811>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@157362 91177308-0d34-0410-b5e6-96231b3b80d8
