[11u] RFR (S) 8214922: Aarch64: Add vectorization support for fmin/fmax

[Volker Simonis]

Hi Dmitry,

in general, the downport looks good to me.

I only wonder if we shouldn't integrate the format changes from
8241911 which were skipped in December when 8241911 was downported
[1,2] because at that time this change wasn't in 11u. I'm fine either
way and leave the final decision to the 11u maintainers.

Thank you and best regards,
Volker
