You can reproduce the problem with, for example:

  echo '#include <arm_neon.h>' | clang -target arm64-linux-gnu -arch +neon 
-fsyntax-only -x c - -fno-lax-vector-conversions

I've cleaned up all our other intrinsics headers to be clean under at least 
`-flax-vector-conversions=integer`. I'll be switching the default for all 
targets other than ARM NEON to that imminently. (It'll take a bit more work to 
be able to switch to `-fno-lax-vector-conversions` by default, but getting 
there should be our goal.)

I've filed PR43341 for this issue.
