Fix ldbl-128 cos range reduction near pi/2 (bug 15429).
Fix ldbl-128ibm cos range reduction near pi/2 (bug 15359).
Add more comments to dlclose() algorithm.

less than immediately obvious. This patch adds two bits
of comments that explain why you start the dependency
search at l_initfini[1], and why you need to restart
the search.
