There aren't any linker changes.  Linking should fail when an
application tries to link shaders with conflicting layouts.

The gl_FragDepth layout should get propagated up into the
gl_fragment_program in the same way as the gl_FragCoord layout.  The
setting in gl_fragment_program should be an enum instead of a set of
distinct bit flags (as is used in ir_variable).
