JDK-8267806 - C1: Relax inlining checks for not yet initialized classes
Description
JDK-8267806 introduced a regression where invokedynamic call site linker can be left not inlined by C1 (even though it is marked with @ForceInline annotation):
 
  @ 3   java.lang.invoke.Invokers$Holder::linkToTargetMethod (9 bytes)   not inlineable

Before JDK-8267806 it was always inlined:
  @ 3   java.lang.invoke.Invokers$Holder::linkToTargetMethod (9 bytes)   force inline by annotation
Comments
Fix Request (17u): Should get backported for parity with 17.0.4-oracle. Applies cleanly. Nightly tests have passed.
