arm: Fix the clang specific version of the assembly (#556)

Also fix the same error in the comment for the non-clang case.
That typo there seems to have existed since the code was written
in that form, in e7f15f60e86 - and when the clang specific codepath
was added in e3d2812ce43, the typo in the comment made it into the
actual code.
