Make libm-test support ALL_RM_TEST with AUTO_TESTS_*.

This patch continues improvements to all-rounding-mode libm testing by
making testing with ALL_RM_TEST support test results from
auto-libm-test-out.  gen-libm-test.pl is adapted to generate
appropriate output with results for each rounding mode, with
AUTO_TESTS_* calls no longer specifying a rounding mode.  Where there
were separate functions in libm-test.inc to test a function in each
rounding mode, using AUTO_TESTS_* to list the tests for each rounding
mode, those are converted to using ALL_RM_TEST (so generally this
patch doesn't change the sets of tests run in each rounding mode,
except that in various cases special-case tests given directly in
libm-test.inc were previously run only for round-to-nearest, and now
are run for all rounding modes).

Tested x86_64 and x86.

	name as argument to AUTO_TESTS_* and pass results for all rounding
	modes to parse_args.
