Subject: [PATCH] testsuite: Be more informative for ICEs

For example, for the two (FAIL, XFAIL)
'gcc/testsuite/lib/gcc-dg.exp:gcc-dg-test-1' cases:

    -FAIL: g++.dg/modules/xtreme-header-3_a.H -std=c++17 (internal compiler error)
    +FAIL: g++.dg/modules/xtreme-header-3_a.H -std=c++17 (internal compiler error: tree check: expected var_decl or function_decl or field_decl or type_decl or concept_decl or template_decl, have namespace_decl in get_merge_kind, at cp/module.cc:10072)

    -FAIL: gfortran.dg/gomp/clauses-1.f90   -O  (internal compiler error)
    +FAIL: gfortran.dg/gomp/clauses-1.f90   -O  (internal compiler error: Segmentation fault)

    -XFAIL: c-c++-common/goacc/kernels-decompose-ice-1.c (internal compiler error)
    +XFAIL: c-c++-common/goacc/kernels-decompose-ice-1.c (internal compiler error: in lower_omp_target, at omp-low.c:13147)

    -XFAIL: g++.dg/cpp1z/constexpr-lambda26.C  -std=c++17 (internal compiler error)
    +XFAIL: g++.dg/cpp1z/constexpr-lambda26.C  -std=c++17 (internal compiler error: in cxx_eval_constant_expression, at cp/constexpr.c:6954)

That allows for more easily spotting when during development you're trading one
ICE for another.

	gcc/testsuite/
	* lib/fortran-torture.exp (fortran-torture-compile)
	(fortran-torture-execute): Be more informative for ICEs.
	* lib/gcc-defs.exp (${tool}_check_compile): Likewise.
	* lib/gcc-dg.exp (gcc-dg-test-1): Likewise.
	* lib/go-torture.exp (go-torture-compile, go-torture-execute):
	Likewise.
