Silence some CMake 3.3 dev warnings in compiler-rt
Fix a trivial instance of CMP0054 that came up on llvmdev.
The other warnings were CMP0057, which is about using the same file as a
MAIN_DEPENDENCY multiple times. The old behavior hasn't been a problem
yet, so I silenced the warning and filed PR23595 to document the issue
if someone cares.
