[Jonathan Wakely]

Tested powerp64le-linux. Pushed to trunk.

-- >8 --

My change in r14-8181-g665a3ff1539ce2 was incomplete as there's a second
place using CTAD with the _Utf32_view alias template. This fixes it.

libstdc++-v3/ChangeLog:

        * include/std/format (_Spec::_M_parse_fill_and_align): Do not
        use CTAD for _Utf32_view.
