Make tests expect the (correctly) emitted warnings using the WARNING directive. This directive is non-functional now, but will be recognised by test_errors.py when D125804 is landed. This patch is a preparation for D125804. For most tests, we add missing WARNING directives for emitted warnings, but there are exceptions: - for int-literals.f90 and resolve31.f90 we pass -pedantic to the frontend driver, so that the expected warnings are actually emitted. - for block-data01.f90 and resolve42.f90 we change the tests so that warnings, which appear unintentional, are not emitted. While testing the warning in question (padding added for alignment in common block) would be desired, that is beyond the scope of this patch. This warning is target-dependent.
