8312425: [vectorapi] AArch64: Optimize vector math operations with SLEEF

[Hamlin-Li]

Hi,
Can you help to review the patch? Previously it's #18605.
This pr is based on #20781.

Thanks!

Test

tests:

• test/jdk/jdk/incubator/vector/
• test/hotspot/jtreg/compiler/vectorapi/

options:

• -XX:UseSVE=1 -XX:+EnableVectorSupport -XX:+UseVectorStubs
• -XX:UseSVE=0 -XX:+EnableVectorSupport -XX:+UseVectorStubs
• -XX:+EnableVectorSupport -XX:-UseVectorStubs

Performance

Tests

jmh tests are test/micro/org/openjdk/bench/jdk/incubator/vector/operation/ from vectorIntrinsics branch in panama-vector. It's good to have these tests in jdk main stream, I will do it in a separate pr later. (These tests are auto-generated tests from some script&template, it's good to also have those scrip&template in jdk main stream, but those scrip&template generates more other tests than what we need here, so better to add these tests and script&template in another pr).

Options

• +intrinsic: 'FORK=1;ITER=10;WARMUP_ITER=10;JAVA_OPTIONS=-XX:+UnlockExperimentalVMOptions -XX:+EnableVectorSupport -XX:+UseVectorStubs'
• -intrinsic: 'FORK=1;ITER=10;WARMUP_ITER=10;JAVA_OPTIONS=-XX:+UnlockExperimentalVMOptions -XX:+EnableVectorSupport -XX:-UseVectorStubs'

Performance data

I have re-tested, there is no much difference from #18605, so please check performance data in that pr.
