prevent an llvm developer from mistakenly thinking that just because the intrinsic has volatile flags that volatile operations can be converted to or folded into them. Platforms may rely on volatile loads and stores of natively supported data width to be executed as single instruction. When compiling C, this expectation likely holds for l-values of volatile primitive types with native hardware support, but not necessarily for aggregate types. The frontend upholds these expectations, which are not specified in the IR. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173974 91177308-0d34-0410-b5e6-96231b3b80d8
