A simple implementations of breadcrumbs tracking of GPU progress
intended to be the last resort when debugging unrecoverable hangs.
For best results use Vulkan traces to have a predictable place of hang.
Requires compilation with TU_BREADCRUMBS_ENABLED=1. See tu_cs_breadcrumbs.c
for details on how to use this feature.

It moves the explicit clamping of incoming Z from vertex stages
after interp, to the depth clamp function.
It adds support to the depth clamp function to restrict incoming
Z values to 0..1 range.
It fixes the depth test conversions to allow unrestricted depth
values.

For unrestricted depth ranges, depth clear values for unorm buffers
need to be explicitly clamped. However this has to happen in the
driver when we know the depth buffer format, not at the API level.
Just add clamps to the non-f32 cases and separate it out.

GLES always clamps for 32-bit float buffers, GL doesn't require
it but setting this per API causes virgl to fail some tests.
To fix is properly we'd need to introduce a CAP to expose
this between host/guest.

This tells the drivers to expect depth values outside the 0..1 range.
This is used for support VK_EXT_depth_range_unrestricted, but could
also be used for GL_NV_depth_buffer_float in GL.

Combine shade_quads_all() and shade_quads_mask() into new
shade_quads() function which takes a mask parameter. It calls either
jit_function[RAST_WHOLE] or jit_function[RAST_EDGE_TEST] depending on
the mask argument.

Some of these are actually bugfixes, some like the drawcall information
are just for autotune so they are just performance fixes. However this
