[PATCH][testsuite/guality] Run guality tests with Og

[Tom de Vries]

Hi,

we advertise Og as the optimization level of choice for the standard
edit-compile-debug cycle, but do not run the guality tests for Og with the
default torture options.

This patch ensures that we test -Og in the guality tests.

F.i., for gcc.dg/guality there are 45 fails for Og (while there are none for
O1), in these test-cases:
...
gcc.dg/guality/pr54200.c
gcc.dg/guality/pr54970.c
gcc.dg/guality/pr56154-1.c
gcc.dg/guality/pr59776.c
gcc.dg/guality/sra-1.c
...

Tested gcc.dg/guality on c-only compiler, currently doing bootstrap and
reg-test on x86_64.

OK for trunk if no issues found during testing?

Thanks,
- Tom

2018-07-13  Tom de Vries  <tdevr...@suse.de>

        * lib/gcc-gdb-test.exp (guality_minimal_options): New proc.
        * g++.dg/guality/guality.exp: Ensure Og is part of torture options.
        * gcc.dg/guality/guality.exp: Same.
        * gfortran.dg/guality/guality.exp: Same.
