commit 7b8f20ec5505a25958bcd98aabe73a7ca2b6cbba

prog_to_nir: Fix fragment depth writes.
In the ARB_fragment_program specification, the result.depth output
variable is treated as a vec4, where the fragment depth is stored in the
.z component, and the other three components are undefined.
This is different than GLSL, which uses a scalar value (gl_FragDepth).
To make this consistent for driver backends, this patch makes
prog_to_nir use a scalar output variable for FRAG_RESULT_DEPTH,
moving result.depth.z into the first component.
Fixes Glean's fragProg1 "Z-write test" subtest.
