 1.5  16-May-2025  rillig tests/lint: test multiple attributes on enums, functions and labels

The grammar rule 'gcc_attribute_specifier_list:
gcc_attribute_specifier_list gcc_attribute_specifier' was not covered
before.
 1.4  28-Mar-2023  rillig branches: 1.4.2;
lint: warn about extern declarations outside headers

 1.3  28-Apr-2022  rillig lint: revert resolving grammar conflicts for labeled statements

Restore the grammar rule for labeled_statement as it was before cgram.y
1.400 from 2022-04-24. This allows labels with attributes again. Fix
the wrong interpretation in the tests; the attributes belong to the
label, not to the statement.

Today in the morning, when I thought that the change in cgram.y 1.400
were innocent, I accidentally ran lint only with the options '-Sw' but
forgot the option '-g' for GNU mode. Without that option, the token
'__attribute__' is unknown, which unsurprisingly leads to lots of syntax
errors, and these didn't change with that commit. The actual change was
only visible in GNU mode.
 1.2  11-Jul-2021  rillig lint: support __attribute__((hot))

The corresponding attribute 'cold' was already added in cgram.y 1.84
from 2016-12-29.
 1.1  06-Jul-2021  rillig tests/lint: add tests for GCC __attribute__

Before fixing the wrong handling of __attribute__ that is demonstrated
at the end of gcc_attribute.c, ensure that the attribute handling works
in the most basic cases.

Lint currently accepts __attribute__ in more places than it should.
This leads to some ambiguities in the grammar.
