By reducing redundant verbiage, this change makes finding the actionable
info in (what used to be) a possibly-long list of warnings easier to see.
compiler/unused_imports.m:
Instead of generating a separate message for each unused import_module
or use_module declaration in a module, classify those declarations
into four categories, and generate just one error_spec for each
nonempty category.
The four categories are in a 2x2 matrix, based on
- whether the declaration is import_module or use_module, and on
- whether the module is unused in the whole module, or just in the
interface.
tests/warnings/bug412.m:
Change the code of this test slightly to add an unused module
that is the sole one it its category, to test both the code for
reporting individual imports and the code for reporting imports in bulk.
tests/warnings/bug412.err_exp:
Expect the warning for the new category, and expect the single bulk warning
for the other unused imports, instead of one warning per import.
