It turns out the simulator was not treating this bit the same as the RPi,
and I'd forgotten to remove it when turning on early Z. The result was
that you'd get big chunks of your rendering missing.
This reverts commit 0543630d0b.
It caused flickering artifacts in Steam games such as Team Fortress 2 or
Left 4 Dead 2.
We could probably only enable this optimization by also making sure the
shader code only uses either SI_PARAM_LINEAR_CENTROID or
SI_PARAM_LINEAR_CENTER, not both. This would probably require a shader
variant.
Sorry I didn't remember this when reviewing the reverted change.

The function was also moved to the header so that it could be inlined at
the two call sites. Without this, 32-bit also needs to pull the
parameter from the stack. This means there is a push, a call, a move,
and a ret added to a two instruction function. The above code shows the
function with __attribute__((regparm=1)), but even this adds several
extra instructions. There is also an extra instruction on 64-bit to
move the parameter to %eax for the subtract.

Before we were always coping from the buffer being mapped into the

the data is going to be junk after we unmap so there's no point in doing

commit allows those values to be properly propagated.
Also, this helps some synmark shaders because it allows us to copy
propagate a 0x00000000UD into a 0.0F in a load_payload, which then lets us
combine 4 load_payloads.
