    Fix PR target/99184: Wrong cast from double to 16-bit and 32-bit ints

    this patch fixed PR target/99184 which incorrectly rounded during 64-bit
    (long) double to 16-bit and 32-bit integers.

    The patch just removes the respective roundings from
    libf7-asm.sx::to_integer and ::to_unsigned.  Luckily, LibF7 does nowhere
    use respective functions internally, the only user is in libf7.c::f7_exp

    which reads

       f7_round (qq, qq);
       int16_t q =3D f7_get_s16 (qq);

    so that f7_get_s16() operates on an already rounded value, and therefore
    this code works unaltered with or without rounding in to_integer.

            PR target/99184
    libgcc/config/avr/libf7/
            * libf7-asm.sx (to_integer, to_unsigned): Don't round 16-bit
            and 32-bit integers.=
