[Arm64] Add ASIMD pairwise reduce instructions

[echesakov]

This adds the following Arm64 instructions:

• fmaxp
• fmaxnm
• fmaxnmp
• fmaxnmv
• fmaxv
• fminp
• fminnm
• fminnmp
• fminnmv
• fminv
• smaxp
• sminp
• umaxp
• uminp

I validate that the encodings are right by comparing the output of JIT dump with WinDbg u and ALL_ARM64_EMITTER_UNIT_TESTS macro defined.

In addition, I fixed the emitter tests for smaxv, sminv, umaxv, uminv, trn1, trn2, uzp1, uzp2, zip1, zip2.

Looks Good

After multiple attempts to retry runtime (Libraries Test Run checked coreclr OSX x64 Debug) continues failing with

@dotnet/runtime-infrastructure Is this a known/tracked issue?

When I tried to open some of the links in the failure log I got either

Executed on dci-mac-build-042.local
/bin/sh: /tmp/helix/working/C9EB0ADC/p/scripts/bbb19dec871d44408dab06396740fd38/execute.sh: Permission denied

or 404 error.

I am merging this change anyway since it doesn't affect x64 side of runtime.

[trylek]

I believe @ViktorHofer mentioned earlier today there's a known "permission denied" issue hitting OSX runs overall.

[safern]

Yeah, that issue is tracked here: https://github.com/dotnet/core-eng/issues/8971
