[PATCH, testsuite]: Add dg-error for unsupported floating suffix

[Uros Bizjak]

Hello!

Attached patch fixes following testsuite failure

FAIL: g++.dg/cpp0x/gnu_fext-numeric-literals.C (test for excess errors)
FAIL: g++.dg/cpp0x/std_fext-numeric-literals.C (test for excess errors)

on targets that don't support Q and W floating suffixes.

2012-11-15  Uros Bizjak  <ubiz...@gmail.com>

        * g++.dg/cpp0x/gnu_fext-numeric-literals.C: Add dg-error directive
        for unsupported non-standard suffix on floating constant.
        * g++.dg/cpp0x/std_fext-numeric-literals.C: Ditto.

Tested on alphaev68-pc-linux-gnu and x86_64-pc-linux-gnu.

OK for mainline?

Uros.
