This option can be used to split AOT kernel generation into two rounds:
* The 1st round uses CFE to parse source files and generate intermediate
dill file in *non-AOT* mode.
* The 2nd round loads intermediate dill file and applies AOT global
transformations, then generates final dill file.
Each round is faster than one-shot generation of a dill file in AOT mode.
In order to use this 2-round compilation, command
gen_kernel <other-options> --aot -o output.dill main.dart
should be replaced with the following 2 commands:
gen_kernel <other-options> --no-aot -o intermediate.dill main.dart
gen_kernel <other-options> --aot --from-dill intermediate.dill -o output.dill main.dart
