This reverts commit 9413bdc381112711a7beb6d6b8d8fc4b4ff6ca01.
That commit broke the fate HEVC tests - unfortunately I only
tested checkasm for that patch, and that function is still
lacking checkasm coverage.

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.
