Test rint and nearbyint with same inputs, in all rounding modes

Subject: Test rint and nearbyint with same inputs, in all rounding modes
Authentication-results: sourceware.org; auth=none
This patch arranges for rint and nearbyint to be tested by
libm-test.inc with the same inputs (previously each had some test
inputs the other didn't, although there was a lot of overlap as well),
and for nearbyint to be tested in all rounding modes where previously
it was only tested in round-to-nearest mode.  The expected results are
the same in each mode, except that rint is expected to have "inexact"
exceptions for non-integer input and nearbyint is expected not to have
those exceptions.

Tested x86_64 and x86.

2014-03-17  Joseph Myers  <joseph@codesourcery.com>

	* math/libm-test.inc (nearbyint_test_data): Include all tests used
	for rint.  Include results for all rounding modes.
	(nearbyint_test): Use ALL_RM_TEST.
	(rint_test_data): Include all tests used for nearbyint.
