[asancov] Write coverage directly to a memory-mapped file. This way does not require a __sanitizer_cov_dump() call. That's important on Android, where apps can be killed at arbitrary time. We write raw PCs to disk instead of module offsets; we also write memory layout to a separate file. This increases dump size by the factor of 2 on 64-bit systems. llvm-svn: 209653
