Issue: There is the need to both specify only applying passes to certain instances/modules/generators instead of all of them.

Proposal:

Be able to specify a filter for applying passes "--filter *" or "--filter -*"
Add ability to mark instances/modules/generators as either whitelisted or blacklisted for a particular pass
Have a priority ordering where instances have highest priority, and generators have lowest priority

This is vaguely similar to the positive and negative globs in https://clang.llvm.org/extra/clang-tidy/#using-clang-tidy

This is a step towards having a pass framework with custom filtering options.

Immediate usecases:
-inlining of particular modules or instances
-flatten-types of particular modules.
