    testsuite: Fix gfortran.dg/ieee/signaling_?.f90 tests for x86 targets
    
    As stated in signaling_?.f90 tests, x86-32 ABI is not suitable to
    correctly handle signaling NaNs.  However, XFAIL is not the correct choice
    to disable these tests, since various optimizations can generate code
    that avoids moves from registers to memory (and back), resulting
    in the code that executes correctly, producing spurious XFAIL.
    These tests should be disabled on x86-32 using { ! ia32 } dg-directive
    which rules out x32 ilp32 ABI, where tests execute without problems.
    
    Please note that check_effective_target_ia32 test tries to compile code that
    uses __i386__ target-dependent preprocessor definition, so it is guaranteed
    to fail on all non-ia32 targets.

    gcc/testsuite/ChangeLog:
    
            * gfortran.dg/ieee/signaling_1.f90 (dg-do):
            Run only on non-ia32 targets.
            * gfortran.dg/ieee/signaling_2.f90 (dg-do): Ditto.
            * gfortran.dg/ieee/signaling_3.f90 (dg-do): Ditto.
