      Description

      Startup profiles and exception microbenchmarks suggests CompiledMethod::get_deopt_original_pc and ::is_deopt_entry are hot in frame::sender, and could be profitably inlined.

      Doing so grows the JVM size by ~20Kb (linux-x64), but improves startup and improves various exception throwing microbenchmarks by 2-5%
