RFR: 8304928: Optimize ClassDesc.resolveConstantDesc [v2]

[Chen Liang]

> This patch optimizes ClassDesc.resolveConstantDesc for array classes. Otherwise, the performance of reference class resolution remain unchanged.
> 
> A benchmark comparing resolution for reference arrays, primitive arrays, and class or interfaces is included in this patch, and the result comparison on my machine is available at https://jmh.morethan.io/?gists=21c462f4879f6166b3308a41c092d51e,1aeae6ff40a129f89dbfedcb874cfd37
