Add more tests of pow.
Prompted by a gcc-patches discussion, this patch adds tests of pow for the cases where pow (x, 0.5) is required to return a different result from sqrt (x), as those cases were previously missing from the tests (although they worked correctly). Tested for x86_64 and x86. * math/auto-libm-test-in: Add another test of pow. * math/auto-libm-test-out: Regenerated. * math/libm-test.inc (pow_test_data): Add another test.
