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.
