When targeting darwin, clang requires commas between arguments,
while the no-comma form is allowed for other targets.

Since Xcode 9.3, the bundled clang supports altmacro and doesn't
require using gas-preprocessor any longer.

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.

Vanilla clang supports altmacro since clang 5.0, and thus doesn't
require gas-preprocessor for building the arm assembly any longer.

However, the built-in assembler doesn't support .dn directives.

This readds checks that were removed in d7320ca3, when
the last usage of .dn directives within libav were removed.

Alternatively, the assembly could be rewritten to not use the
.dn directive, making it available to clang users.

See the earlier fix for movtextdec for details. The equivalent bug is
present on the encoder side as well.

We need to track the text length in 'characters' (which seems to really
mean codepoints) to ensure that styles are applied across the correct
ranges.
