Clang supports the macro expansion counter (used for making unique labels within macro expansions), but not when targeting darwin. Convert uses of the counter into normal local labels, as used elsewhere. Since Xcode 9.3, the bundled clang supports altmacro and doesn't require using gas-preprocessor any longer.
