Upgrade Chalk to 0.21

Two commits here. First commit actually does the upgrade. Second commit has some changes to make more tests in compare-mode=chalk pass.

The `PlaceholdersCollector` and `RegionsSubstitutor` bits are bit a hacky, but only insomuch as `ParamsSubstitutor` is. These won't be needed eventually.
