Nikita Popov 0670491950 Don't add empty target features for target-cpu=native on macOS ...

LLVM does not support host feature detection (only host cpu
detection) on apple platforms. As such, the returned feature
string will be empty. Adding this empty string to the target-features
attribute results in a verifier error on LLVM 22.

Fix this by not adding the empty string to the target features.
The reason why this was not caught by the target-cpu-native test
is that it requires a function that adds *some* target features,
otherwise the attribute is omitted entirely. We achieve this with
a somewhat peculiar construction that enables `neon` if it's
already enabled. (This is to avoid enabling it on softfloat targets.)
