Here is a recently developed set of IEEE test vectors that includes
the set from the thesis of Coonen, some values from ucbtest, and extensions
to quad precision. Unfortunately the program was written for C++
version n-1 and I have C++ version n, a hopeless situation. It might
be useful for a C++ enthusiast to work on the program.

Testing the decimal constants extracted from the 80-bit and 128-bit
series of these vectors seemed to generate no errors that were outside the
IEEE spec limits. I also extracted and checked all of the decimal
constants from the quad precision glibc math library, about 1700 numbers;
they all come out correctly rounded now.
