I have ccoshl and ccosl implemented, but need to do some testing.

Things that are missing ctanhl, ctanl, csinhl, and csinl.  I have an
old implementation of csinhl/csinl, but Bruce had some concerns with
handling of NaN and +-inf.  Need to dig up some old emails.

tgammal, powl, and cpow[fl] are a mess as the people who committed
code for these functions seem to have no interest in floating point
math on FreeBSD.
