    libstdc++: Don't use std::__is_scalar in std::valarray initialization
[PR115497]

    This removes the use of the std::__is_scalar trait from <valarray>,
    where it can be replaced by __is_trivial. It's used to decide whether we
    can use memset to value-initialize valarray elements, but memset is
    suitable for any trivial types, because value-initializing them is
    equivalent to filling them with zeros.

    This is another step towards removing the class templates in
    <bits/cpp_type_traits.h> that conflict with Clang built-in names.

    libstdc++-v3/ChangeLog:

            PR libstdc++/115497
            * include/bits/valarray_array.h (__valarray_default_construct):
            Use __is_trivial(_Tp). instead of __is_scalar<_Tp>.
