[PATCH] gcc.dg/noncompile/ cleanup

[Marek Polacek <polacek at redhat dot com>]

This patch is a cleanup of tests in gcc.dg/noncompile/ directory.
See https://gcc.gnu.org/ml/gcc-patches/2014-09/msg02656.html for more info.

Tested on x86_64-linux: vanilla results == results with this patch ==
results with this patch and gnu11 as a default.

Ok?
