    Fix PR 101453: ICE with optimize and large integer constant

    The problem is the buffer is too small to hold "-O" and
    the interger.  This fixes the problem by use the correct size
    instead.

    Changes since v1:
    * v2: Use HOST_BITS_PER_LONG and just divide by 3 instead of
    3.32.

    OK? Bootstrapped and tested on x86_64-linux with no regressions.

    gcc/c-family/ChangeLog:

            PR c/101453
            * c-common.c (parse_optimize_options): Use the correct
            size for buffer.
