RFR: 8299061: Using lambda to optimize GraphKit::compute_stack_effects()

[Xin Liu]

Some bytecodes donot need rsize in GraphKit::compute_stack_effects(). 
This change defines rsize as a lambda and avoid computation if it's not in use. 

We utilize CTW($openjdk/test/hotspot/jtreg/testlibrary/ctw/dist) to test this patch.
We compile 2 builtin modules: java.base and jdk.compiler(javac).


JAVA_OPTIONS="-XX:+CITime -XX:-TieredCompilation" ./ctw.sh modules:java.base
JAVA_OPTIONS="-XX:+CITime -XX:-TieredCompilation" ./ctw.sh modules:jdk.compiler


For java.base module, the average compilation speed increases from 12011 bytes/s to 12301 bytes/s, or +2.41%.
For jdk.compiler module, the average compilation speed is almost same(+0.16%)
