Factor out some common code from the libm tests. This is a bit messy
because different tests have different ideas about what it means to be
"close enough" to the right answer, depending on the properties of the
function being tested. In the process, I fixed some warnings and
added a few more 'volatile' hacks, which are sufficient to make all
the tests pass at -O2 with clang.

Fix some regressions caused by the switch from gcc to clang. The fixes
are workarounds for various symptoms of the problem described in clang
bugs 3929, 8100, 8241, 10409, and 12958.

The regression tests did their job: they failed, someone brought it
up on the mailing lists, and then the issue got ignored for 6 months.
Oops. There may still be some regressions for functions we don't have
test coverage for yet.

Tests for cancellation in fma(). Also include more tests for 128-bit
long doubles. Thanks for clusteradm (simon) for making the needed
hardware available.

Add some tests for double-rounding bugs in fma().

signbit() returns nonzero for negative arguments, but we shouldn't assume
that it always returns the same nonzero value.

Add some tests for fma(), fmaf(), and fmal().
