> This patch adds fast clinit barrier in the interpreter when resolving cp entry for a static field.
> 
> Testing: tested x86-64 by running `hotspot_runtime` group
> Specifically, `runtime/clinit/ClassInitBarrier.java` fails if the block for adding `clinit_barrier` is commented out in `TemplateTable::resolve_cache_and_index_for_field`
