Test most libm functions in all rounding modes.
This patch makes libm-test.inc tests of most functions use ALL_RM_TEST unless there was some reason to defer that change for a particular function. I started out planning to defer the change for pow (bug 16315), cexp / ccos / ccosh / csin / csinh (likely fallout from exp, bug 16284) and cpow (exact expectations for signs of exact zero results not wanted). Testing on x86_64 and x86 showed additional failures for acosh, cacos, catan, catanh, clog, clog10, jn, log, log10, log1p, log2, tgamma, yn, so making the change for those functions was deferred as well, pending investigation to show which of these represent distinct bugs (some such bugs may already be filed) and appropriate fixing / XFAILing. Failures include wrong signs of zero results, errors slightly above the 9ulp bound (in such cases it may make sense for functions to set round-to-nearest internally to reduce error accumulation), large errors and incorrect overflow/underflow for the rounding mode (with consequent missing errno settings in some cases). It's possible some could be issues with test expectations, though I didn't notice any that were obviously like that (I added NO_TEST_INLINE for cases that were failing for ildoubl on x86 and where it seemed reasonable for them to fail for the fast-math inlines). There may of course be failures on other architectures for functions that didn't fail on x86_64 or x86, in which case the usual rule applies: file a bug (preferably identifying the underlying problem function, in cases where function A calls function B and a problem with function B may present in the test results for function A) if not already in Bugzilla then fix or XFAIL. Tested x86_64 and x86 and ulps updated accordingly. * math/libm-test.inc (asinh_test): Use ALL_RM_TEST. (atan_test): Likewise. (atanh_test_data): Use NO_TEST_INLINE for two tests.
