ConfiguredTargetFunction#getDynamicConfigurations: halve the number of AttributeAndLabel instantiations. This shaves 25% off the method's execution time in --experimental_dynamic_configs=notrim mode.
This isn't a crucial optimization, since getDynamicConfigurations is already fast. Profiling:
$ bazel shutdown; bazel build --nobuild //testapp:cc
--experimental_dynamic_configs=notrim
shows getDynamicConfigurations takes 1.3% of the analysis phase's CPU time before this change and 1.0% after. Before this change, AttributeAndLabel instantiation took 44% of the method's CPU time. After: 30%.
Profiling done with JProfiler.
