[PATCH] Move dg-error directives to relevant lines

[Jonathan Wakely]

A few more tests that use hardcoded dg-error line numbers, but could
use implied ones.

        * testsuite/19_diagnostics/error_code/operators/bool_neg.cc: Move
        dg-error to relevant line.
        * testsuite/19_diagnostics/error_condition/operators/bool_neg.cc:
        Likewise.
        * testsuite/20_util/ratio/cons/cons_overflow_neg.cc: Likewise.

Tested powerpc64-linux, committed to trunk.
