Joseph Myers 7fda568229 Move various TEST_c_c tests from libm-test.inc to auto-libm-test-inc. ...

This patch moves tests of ccos, ccosh, cexp, clog, csqrt, ctan and
ctanh to auto-libm-test-in, adding the required support to
gen-auto-libm-tests.  Other TEST_c_c functions aren't moved for now
(although the relevant table entries are put in gen-auto-libm-tests
for it to know how to handle them): clog10 because of a known MPC bug
causing it to hang for at least some pure imaginary inputs (fixed in
SVN, but I'd rather not rely on unreleased versions of MPFR or MPC
even if relying on very recent releases); the inverse trig and
hyperbolic functions because of known slowness in special cases; and
csin / csinh because of observed slowness that I need to investigate
and report to the MPC maintainers.  Slowness can be bypassed by moving
to incremental generation (only for new / changed tests) rather than
regenerating the whole of auto-libm-test-out every time, but that
needs implementing.  (This patch takes the time for running
gen-auto-libm-tests from about one second to seven, on my system,
which I think is reasonable.  The slow functions would make it take
several minutes at least, which seems unreasonable.)

Tested x86_64 and x86 and ulps updated accordingly.

	csqrt, ctan and ctanh.
