STATE_BASE_ADDRESS specifies a maximum size of the dynamic state
section, beyond which data supposedly reads back as 0. On Gen8+,
we were programming it to the size of the buffer. This worked fine
until we started growing the state buffer in commit 2dfc119f22.
When the state buffer grows, the value in STATE_BASE_ADDRESS becomes
too small, and our state beyond STATE_SZ bytes would read back as 0.
To avoid having to update the value, we program it to MAX_STATE_SIZE.
We used to program the upper bound to the maximum on older hardware
anyway, so programming it too large isn't a big deal.
Bogus SURFACE_STATE can easily lead to GPU hangs and misrendering.
DiRT Rally was hitting the statebuffer growth path, and suffered from
bad texture corruption and GPU hangs (usually around the same time).
This patch fixes both issues.
Fixes: 2dfc119f22 "i965: Grow the batch/state buffers if we need space and can't flush."

Commit 78942e ("mesa: shrink VERT_ATTRIB bitfields to 32 bits") uses
vs_prog_data->vs_inputs as if it were a 32-bit unsigned integer.
But actually it is a 64-bit integer, and as such it is used in other
parts of Mesa code. It is worth to note that bits from the entire range
are used, and not only 32-bits. This is due our implementation for
handling 64-bit dual-slot input attributes, which requires to use a
larger bitfield to manage them.
This commit reverts the changes done in brw_draw_upload.c, keeping the
rest of the changes.
This fixes the following tests:
- KHR-GL45.enhanced_layouts.varying_array_locations
- KHR-GL45.enhanced_layouts.varying_locations

This is more inline with what the functions name suggests it should
do, and makes the code much easier to follow.
This will also make adding uniform packing support much simpler.

This fixes hangs on cayman with
tests/spec/arb_tessellation_shader/execution/trivial-tess-gs_no-gs-inputs.shader_test
This has a single if/else in it, and when this peephole activated,
it would set the jump target to NULL if there was no instruction
after the final POP. This adds a NOP if we get a jump in this case,
and seems to fix the hangs, so we have a valid target for the ELSE
instruction to go to, instead of 0 (which causes infinite loops).

This is cleaner than using a non-standard memclear macro (which does a
memset to 0) and then initializing fields after the fact. We move the
declarations to where we initialized the fields. While we're at it, we
move the declaration of 'ret' that goes with the ioctl, eliminating the
declaration section altogether.

These were moved to src/intel/common/gen_debug.h, but they are not
common code. They assume that brw_context or gl_context variables
exist, named brw or ctx. That isn't remotely true outside of i965.
