Since SSBOs can be written by other GPU threads, copy propagating a read
can cause the value to magically change. SSBO reads are also very
expensive, so doing it twice will be slower.
Haswell, Broadwell, and Skylake had similar results. (Skylake shown)

On GFX8+, there is a bug that affects TC-compatible depth surfaces
when the ZRange is not reset after LateZ kills pixels.
The workaround is to always set DB_Z_INFO.ZRANGE_PRECISION to match
the last fast clear value. Because the value is set to 1 by default,
we only need to update it when clearing Z to 0.0.
We also need to set the depth clear regs and to update
ZRANGE_PRECISION when initializing a TC-compat depth image to 0.
Original patch from James Legg.

If the application asks for the maximum number of fragment input
components (128), use all of them plus some builtins that are
passed in the VUE, then we exceed the maximum number of used VUE
slots (32) and we break one assert that checks this limit.
Also, with separate shader objects, we add CLIP_DIST0, CLIP_DIST1
builtins in brw_compute_vue_map() because we don't know if
gl_ClipDistance is going to be read/write by an adjacent stage.

The UBO push analysis pass incorrectly assumed that all values would fit
within a 32B chunk, and only recorded a bit for the 32B chunk containing
the starting offset.
For example, if a UBO contained the following, tightly packed:
vec4 a; // [0, 16)
float b; // [16, 20)
vec4 c; // [20, 36)
then, c would start at offset 20 / 32 = 0 and end at 36 / 32 = 1,
which means that we ought to record two 32B chunks in the bitfield.
Similarly, dvec4s would suffer from the same problem.
