CMake: make building with /MT an option instead of always forcing it
for release builds. This is a follow-up to r194589. Aaron pointed out that building libraries with /MT and using them in an application that uses a different run-time library can be a bad idea. Move the option to build with /MT behind a CMake option so it can be turned on selectively, such as when building the toolchain installer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194596 91177308-0d34-0410-b5e6-96231b3b80d8
