Metal: disable fastmath less often. Stop disabling fastmath if atan is used in the shader. Application developers will surely prefer the significant performance improvement of the fastmath optimizations over corner-case differences in precision. Make disabling fastmath more precise: only if it's forcibly disabled as a driver bug workaround, or if the shader uses invariance and preserveInvariance is not available. Suppress the test: dEQP-GLES[23].functional.shaders.invariance.lowp.loop_2 which fails when fastmath is enabled for shaders using atan and invariance.
