This involved adding a new substitution called %api_diff_data_dir that when building against a host toolchain, looks in the host toolchain (next to swiftc) rather than in the resource dir. The reason why I need to do this is this allows me to perform a stdlib stage2 build without needing to build swift itself. The only interesting changes here are that I had to add %api_diff_data_dir to a bunch of normal/expected tests and also add %api_diff_data_dir's length to the offsets in rdar31892850.swift.
