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.
