Removing a D3D limitation from SwiftShader
Removing a D3D limitation from SwiftShader

The limitation of not being able to have
different values for stencil and stencilBack
was put in place in Angle because of a D3D
limitation, which we do not have in Swift
Shader, so I doubt we need the same limitation.

FYI, this fixes about 600 dEQP tests.
