Trevor Gross 90c76ad3cb Ignore specific atan2 and sin tests on i586 
There seems to be a case of unsoundness with the `i586` version of
`atan2`. For the following test:

    assert_eq!(atan2(2.0, -1.0), atan(2.0 / -1.0) + PI);atan2(2.0, -1.0)

The output is optimization-dependent. The new `release-checked` profile
produces the following failure:

    thread 'math::atan2::sanity_check' panicked at src/math/atan2.rs:123:5:
    assertion `left == right` failed
      left: 2.0344439357957027
     right: 2.0344439357957027

Similarly, `sin::test_near_pi` fails with the following:

    thread 'math::sin::test_near_pi' panicked at src/math/sin.rs:91:5:
    assertion `left == right` failed
      left: 6.273720864039203e-7
     right: 6.273720864039205e-7

Mark the tests ignored on `i586` for now.
