    varasm: Fix up ICE in narrowing_initializer_constant_valid_p [PR105998]

    The following testcase ICEs because there is NON_LVALUE_EXPR (location
    wrapper) around a VAR_DECL and has TYPE_MODE V2SImode and
    SCALAR_INT_TYPE_MODE on that ICEs.  Or for -m32 -march=3Di386 TYPE_MODE
    is DImode, but SCALAR_INT_TYPE_MODE still uses the raw V2SImode and ICEs
    too.

            PR middle-end/105998
            * varasm.cc (narrowing_initializer_constant_valid_p): Check
            SCALAR_INT_MODE_P instead of INTEGRAL_MODE_P, also break on
            ! INTEGRAL_TYPE_P and do the same check also on op{0,1}'s type.

            * c-c++-common/pr105998.c: New test.
