[Polly][CMake] Exclude isl_config from the polly-check-format target.

pfaffe · pfaffe · commit bbb86719c1aa · 2017-05-15T13:20:26.000Z
Summary: The custom `polly-check-format` target runs clang-format over all source files in the directory tree excluding lib/External. `isl_config.h` is a header file that is generated by CMake in the build directory, and it's not correctly formatted (which I also wouldn't consider necessary, as it is a generated file). If the build directory is actually inside the Polly source directory (which it might be if you're building Polly out-of-tree), that check always fails. Hence this patch excludes this file from the check-format target.
