[jdk11u-dev] RFR: 8285395: [JVMCI] Partial backport of JDK-8220623: InstalledCode

[Severin Gehwolf]

Please review this 11u-only change in the JVMCI area. Latest Graal master introduced a change which overrides `getAddress()` and `getEntryPoint()` in class `InstalledCode`. This isn't an issue in Graal VM CE since labs openjdk is used there which has newer JVMCI level. The same code is present in JDK 13+. I'm only proposing a partial backport since that's sufficient to unbreak the Mandrel build and is a lot less risky than bringing in JDK-8220623 wholesale. See the bug for details.

Testing:
 - [x] jvmci tests
 - [x] Mandrel build with a base JDK including this patch. Builds now, broke earlier.
