compiler/module_imports.m:
The module_timestamp type has long had a field of the need_qualifier type.
For a year or more now, this field has had a big comment on it explaining
why its use here does not match the semantics of the need_qualifier type.
This diff gives this field a new, bespoke type, that is isomorphic
to need_qualifier, but is completely deparate. Document the reason why
I *can't* document the semantics of this new type :-(
compiler/grab_modules.m:
Do the same kind of replacement on values that are used only to set
this field of module_timestamps.
compiler/recompilation.check.m:
compiler/recompilation.usage.m:
Use the values of the new type to make the same decisions we used to make
using values of the need_qualifier type.
tests/recompilation/*.m*:
Bring the programming style of these modules up to date.
tests/recompilation/*.err_exp.2:
Expect the updated line numbers in messages.
Delete the need_qualifier field from timestamps.
