RFR: 8261247: some compiler/whitebox/ tests fail w/ DeoptimizeALot

[Igor Ignatyev]

Hi all,

could you please review this small test-only patch that adds `@requries vm.opt.DeoptimizeALot != true` to `compiler/whitebox/` tests that check if a method gets compiled? such checks can fail intermittently when are `DeoptimizeALot` is used (as the method can get deoptimized before we checked if it was compiled).

testing: 
* [x] `compiler/whitebox/` on `macosx-x64-fastdebug` w/o any flags (17 tests)
* [x] `compiler/whitebox/` on `macosx-x64-fastdebug` w/ -XX:+DeoptimizeALot (6 tests)

Thanks,
-- Igor
