RFR: 8294236: [IR Framework] CPU preconditions are overriden by regular preconditions

Fri Sep 23 09:17:04 UTC 2022

This changeset ensures that all preconditions of a IR test (`applyIf`, `applyIfCPUFeature`, etc.) are evaluated as a logical conjunction to determine whether the test's IR check should be applied.

#### Testing

- tier1-3 (windows-x64, linux-x64, linux-aarch64, and macosx-x64).
- IR framework tests in `test/hotspot/jtreg/testlibrary_tests/ir_framework` (linux-x64).
