This patch optimizes ClassDesc.resolveConstantDesc for array classes. Otherwise, the performance of reference class resolution remain unchanged. https://jmh.morethan.io/?gist=111095eecf7a735fe8c96e4b952b58c1 It also includes a benchmark for MethodTypeDesc resolution, which currently does not yet depend on class desc resolution but can be later optimized if it does switch.
