    d: Fix ICE in when formating a string with '%' or '`' characters (PR98457)

    The percentage character was being confused for a format specifier in
    pp_format(), whilst the backtick character was confused for the
    beginning of a quoted string in expand_d_format().

    Both are now properly escaped to avoid the ICE.

    gcc/d/ChangeLog:

            PR d/98457
            * d-diagnostic.cc (expand_d_format): Handle escaped backticks.
            (escape_d_format): New funtion.
            (verror): Call escape_d_format on prefixing strings.
            (vdeprecation): Likewise.

    gcc/testsuite/ChangeLog:

            PR d/98457
            * gdc.dg/pr98457.d: New test.
