[Hamlin Li]

> Hi,
> Can you help to review this patch?
> 
> https://openjdk.org/jeps/483 introduced aot (class loading/linking) and subsequent prs introduced more features related to it, like preserve adapters(c2i/i2c) and runtime blobs in AOT code cache.
> 
> Riscv should support these features and resolve relative issues.
> 
> ## Test
> 
> ### jtreg
> 
> run tier1/2/3 and hotspot_cds tests, no new failure found compared to master jdk. 
> 
> ### Performance
> 
> perf command to run the simplest Hello world java program:
> * (perf stat -r 100 ${JAVA_HOME}/bin/java -XX:AOTCache=$AOT_CACHE -cp $CLASS_PATH Hello > /dev/null) 2>&1 | grep elapsed
> 
> perf data:
> * (with patch): 0.181730 +- 0.000296 seconds time elapsed ( +- 0.16% )
> * (without patch): 0.196627 +- 0.000227 seconds time elapsed ( +- 0.12% )
