[Bug libstdc++/17140] Floating point output is slow

The power4 segfault occurs in frexpl() in libc, which is a result of calling
__builtin_frexpl() inside std::frexp(long double).  I was wondering if it might
be a problem in long double representation.  I think ppc uses 64 bit long
double, which made me think that it should be calling frexp under the covers
rather than frexpl.

I also created a simple test program for frexp that sems to work for double and
not for long double.

This is making me think the problem isn't in this patch.
