[PATCH] D24071: [compiler-rt] [builtins] Allow building the necessary ARM builtins for MSVC mode with cmake

Even though llvm emits calls to __rt_{s,u}div{,64} when targeting Windows on ARM, it also emits calls to some of these (__moddi3, __umoddi3), making the compiler-rt builtins necessary in this configuration.
