This patchset contains arm64 neon implementation of hscale functions.
Fixed minor style issues and declared C function wrappers as static.
This patchset do not contain the patch for checkasm tool, as the
previous one did. The reason behind it was failing tests on x86 arch
but not on aarch64 or loongarch. Probably the hscale functions on x86
have some bugs. Currently the checkasm tool does not check
the validity of hscale functions on x86 at all. Implementation of hscale
for x86 should be fixed anyway. As it comes to aarch64 the tests were
passing. Attaching a link to fate result in patchwork. After fixing x86
the patch for checkasm could be merged.
