[patch testsuite]: Skip some tests for w64 target

[Kai Tietz]

Hi,

this patch skip some testsuite tests, which are producing an ICE reasoned 
by stack overflow. At the moment gcc executables for w64 have a stack size 
of 8MB set. So some of the tests are failing, because they consume (by 
recursions in gimplifier on expression handling) too much stack. Sadly the 
stack size isn't dynamically as for linux.

        * g++.dg/eh/cleanup1.C: Skip for target x86_64-*-mingw*
        reasoned by stack overflow.
        * gcc.c-torture/compile/limits-declparen.c: Likewise.
        * gcc.c-torture/compile/limits-exprparen.c: Likewise.
        * gcc.c-torture/compile/limits-structnest.c: Likewise.

Is this patch ok to be applied?

Cheers,
Kai
