[Bug testsuite/20567] New: dg-options in gcc.c-torture

["jsm28 at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

Some tests in gcc.c-torture use dg-options inappropriately.

gcc.c-torture/execute ignores dg-options settings, but pr7284-1.c and
wchar_t-1.c use them.  I think the proper fix would be to make that directory
honour dg-options.  If it is made to use the dg harness it might also be
possible to get rid of most of the .x files in c-torture by moving them into
test annotations within the testcase files.

In gcc.c-torture/compile, tests 20031125-1.c, 20031125-2.c, 20031203-1.c and
acc1.c specify -O2.  As the point of the torture tests is to iterate over
different optimization options, tests should not specify any options like -O2
which are included in that iteration; only other special options (such as
-ffast-math for acc1.c).

compile/981006-1.c looks like a diagnostic test and as such (a) should not use
-w, (b) should better be in gcc.dg/torture/.
