> While working on [JDK-8357135](https://bugs.openjdk.org/browse/JDK-8357135), I was reminded that some of the code implementing eager JVMCI compiler initialization (i.e. `-XX:+EagerJVMCI`) is in helper methods such as `JVMCIRuntime::call_getCompiler` that sound general purpose but are only used for eager JVMCI compiler initialization. This PR inlines `JVMCIRuntime::call_getCompiler` and renames `JVMCI::initialize_compiler` to `initialize_compiler_in_create_vm` to make its single use case clearer.

This pull request has now been integrated.
