RFR: 8370489: Some compiler tests miss the @key randomness [v2]

[Saranya Natarajan]

> **Issue:** Some compiler tests uses randomization but does not have `@key randomness` in the jtreg header.
> 
> **Fix:** The list of test cases that did not have  `@key randomness` were listed using  `grep -l "getRandomInstance" -r test/hotspot/jtreg/compiler/ | xargs grep -L "randomness"`. This PR adds `@key randomness` to these tests. 
> 
> **Note:** The following tests that are still listed with  `grep -l "getRandomInstance" -r test/hotspot/jtreg/compiler/ | xargs grep -L "randomness"` after this PR are confirmed to be helper or support file for actual test.
