freedreno/ir3: Drop the max_const on a6xx to 512.

The GLES blob on the p3a limits constlen to 512 between VS and FS across
a6xx gpu ids (615, 630, 640, and 650).  Experimentally, exceeding that
limit in any one stage results in rendering corruption or GPU hangs
(though my most detailed testing had a loop limit in a uniform, so that
may the cause of the hang).  Clamp the limit we use inside of a shader so
we don't exceed it within a stage.

This commit doesn't resovle limiting inter-stage.  Experimentally, I've
found that I can push up to a total of ~768 vec4s between VS and FS on
a630, with or without uniform updates between each draw.  We'll need to do
some shader key-based limiting of constlen at draw time to respect that
limit, but that's left for future work, and this commit is enough for the
google earth case that initiated this work.

freedreno/ir3: Account for driver params in UBO max const upload.

The const state setup needs to be able to push its driver params, so
account for them in the analyze_ubo_ranges.

freedreno/ir3: Stop shifting UBO 1 down to be UBO 0.

It turns out the GL uniforms file is larger than the hardware constant
file, so we need to limit how many UBOs we lower to constbuf loads.  To do
actual UBO loads, we'll need to be able to upload UBO 0's pointer or
descriptor.

freedreno/ir3: Drop unnecessary alignment of pushed UBO size.

The analysis pass gives us vec4-aligned size, and all of our other
constbuf allocations here are in vec4 units, so we can just divide by 16.

freedreno/ir3: Stop pushing immediates once we've filled the constbuf.

If we filled the constbuf up with UBOs, we may need to avoid generating

freedreno: Upload gallium constbufs as needed when referenced as a UBO.

freedreno/a6xx: add early-lrz-late-z mode

Now that we are doing a better job of managing LRZ, add support for the
EARLY_LRZ_LATE_Z mode.  Since we properly disable LRZ write in cases
where we don't know a fragment's z value during the binning pass (or
when blend is enabled in a later draw, meaning we will need the earlier
fragment's color), we can enable a mode that keeps the early-lrz test
when the frag shader has kill/discard.  This will only discard geometry
that is definitely not visible.

This is a pretty big win for games/benchmarks that have a lot of frag
shaders with kill/discard.  More than 10% gain for gfxbench trex/mh and
40% gain for mh31.

OPTIONAL: iris: Perform BLORP buffer barriers outside of iris_blorp_exec() hook.

The iris_blorp_exec() hook needs to be executed under a single
indivisible sync region, which means that in cases where we need to
emit a PIPE_CONTROL for a buffer barrier we won't be able to track the
subsequent commands separately from the previous commands, which will
prevent us from optimizing out subsequent PIPE_CONTROLs if we
encounter the same buffers again.  In particular I've encountered this
situation in some SynMark test-cases which perform lots of BLORP
operations with the same buffer bound as both source and destination
(in order to generate mipmaps): In such a scenario if the source
requires flushing we'd also end up flushing for the destination
redundantly, even though a single PIPE_CONTROL would have been
sufficient.

This avoids a 4.5% FPS regression in SynMark OglHdrBloom and a 3.5%

panfrost: Update MALI_EARLY_Z description

Via the ES3.1 early-z testing force, I've confirmed this bit is e-z.
I've also confirmed e-z must be disabled for global writes, as expected.
