Fragment shaders that require explicit early fragment tests are incompatible with specifying depth and stencil values within the shader. If explicit early fragment tests is specified, remove the depth and stencil outputs from the output structure, and replace them with dummy local variables. Add CompilerMSL:uses_explicit_early_fragment_test() function to consolidate testing for whether early fragment tests are required. Add two unit tests for depth-out with, and without, early fragment tests.
