compiler/error_spec.m:
Delete conditional_spec from the error_spec type, which had
exactly one use left in the compiler. Replace it with a conditional form
of severity_error, which handles that use case.
Rename error_severity to spec_severity, since obviously not all severities
represent errors.
For the same reason, rename error_phase to spec_phase.
compiler/error_util.m:
Export a predicate for write_error_spec.m.
compiler/write_error_spec.m:
Use that export to delete what used to be duplicate code.
compiler/add_pragma.m:
compiler/check_typeclass.m:
compiler/compiler_util.m:
compiler/error_sort.m:
compiler/mark_tail_calls.m:
compiler/parse_error.m:
compiler/parse_item.m:
Conform to the changes above.
