Fix arm_neon.h and arm_fp16.h generation for compiling with std=c89

[dnsampaio]

Summary

The inline attribute is not valid for C standard 89. Replace the argument in the generation of header files with __inline, as well adding tests for both header files.

Looks good to me.

If you want to change it, at least change it properly to use inline.

Same.

Sorry, I don't get the suggestion. Do you mean test if it is C89 and use __inline, else, use inline?

[dnsampaio]

Fix test march triple.

These new changes look good to me.

If you are updating things like this, it's often better to create a new Phab review so it's easier to see it's a new thing (or, in cases like this where the changes are simple and just test updates, they often don't need review). Either way, LGTM. Thanks for the test fix.

I think the suggestion was unintentionally rendered as an underline by phab; and was supposed to be

__inline__

[joerg]

Correct. The protected name is double underscore as both suffix and prefix.

Ok, fixed. Cheers.
