[jdk17] RFR: 8269260: Add AVX512 and other SSE + AVX combinations testing for tests which generate vector instructions

[Vladimir Kozlov]

[8269179](https://bugs.openjdk.java.net/browse/JDK-8269179) bug shows that we (Oracle) don't test enough different vectors instructions on x64.

I suggest to create new HotSpot compiler test groups for such tests and together with jdk_vector (jdk/incubator/vector) group run them with different SSE and AVX HotSpot flags combinations: 

-XX:UseAVX=3 
-XX:UseAVX=2 
-XX:UseAVX=1 
-XX:UseAVX=0 
-XX:UseAVX=0 -XX:UseSSE=3 
-XX:UseAVX=0 -XX:UseSSE=2 (this is minimal setting for 64 bit)


Here my suggesting how to run them on windows-x64-debug and linux-x64-debug: 

hs-tier2: 
  hotspot_vector_1 - run with all flags combinations listed in Description 
  hotspot_vector_2 - run with `-XX:UseAVX=3` only 

hs-tier3: 
  jdk_vector - run with all flags combinations listed in Description 
  hotspot_vector_2 - run with all combinations except `-XX:UseAVX=3`


Tier1 already runs these tests in default mode.

Tested hs-tier1-3 internally.
