## Issue
The test `compiler/ciReplay/TestInliningProtectionDomain.java` still fails with
`--enable-preview` even when using `java.lang.Record` as return class.
## Causes
`java.lang.Record` is part of the migrated value classes that are added to the
class loader if _enable preview_ is on and consequently it gets resolved early,
making `ProtectionDomainTestNoOtherCompilationPrivate` fail.
## Fix
To avoid further potential issues (with another lib class that could
potentially be loaded early in the future) I replaced the `Record` return type
with a new test-local `class SigType {}` in the three `bar()` methods.
Additionally the private-case replay assertion had to be updated to expect
`unloaded signature classes` instead of `disallowed by ciReplay` (`Record` was
resolved early and inlining was explicitly denied by replay. `SigType` is
simply not resolved). The purpose of the test (that replay compilation produces
the same inlining outcome as the normal run) should still be met.
