    middle-end/95118 - fix printing of denormal zero

    This fixes printing a REAL_CST generated from value-numbering
    punning some bits to a real which turns out as zero with big
    negative exponent.  This causes the loop in real_to_decimal_for_mode to
    never terminate.

            * real.c (real_to_decimal_for_mode): Make sure we handle
            a zero with nonzero exponent.

            * gcc.dg/pr95118.c: New testcase.
