Implement flat interpolation qualifier support.

By default vertex shader outputs/fragment shader inputs are
smoothly interpolated. The 'flat' keyword can be used to change
the interpolation to "flat", which basically means that no
interpolation is performed. "flat" is the only interpolation
qualifier accepted for integer types.

This change fixes all shaders/precision dEQP tests as well as a
few fragment output integer format types related tests.
