Previously, const-values output is not supported correctly as it is not captured correctly as a dependency. The load of the input JSON file is loaded via file system directly, that can cause issues like: * False cache hit when the file is changed * Cannot be prefix mapped to allow distributed caching Try to support the input file by: * Correctly capture the input * Create a new driver flag `-const-gather-protocols-list` that can do path remapping correctly in swift-driver rdar://169109358
