Right now, all keys have two things in common: a program string ID and a
sampler_prog_key_data. I'd like to add another thing or two and need a
place to put it. This commit adds a new brw_base_prog_key struct which
contains those two common bits.

This commit moves the sysvals to a separate, new constant buffer
at the end (before the shader constants). It also allows us to
remove the special handling we had for cbuf0, and enables all
constant buffers to support user-specified resources and user
buffers.
v2: (by Kenneth Graunke)
- Rebase on the previous patch to fix system value uploading.
- Fix disk cache num_cbufs calculation
- Fix passthrough TCS to report num_cbufs = 1 so upload actually occurs
- Change upload_sysvals to assert that num_cbufs > 0 when
num_system_values > 0.

Stop using brw_compiler to lower the final binding table indices for
surface access. This is done by simply not setting the
'prog_data->binding_table.*_start' fields. Then make the driver
perform this lowering.
This is a better place to perfom the binding table assignments, since
the driver has more information and will also later consume those
assignments to upload resources.
This also prepares us for two changes: use ibc without having to
implement binding table logic there; and remove unused entries from
the binding table.
Since the `block` field in brw_ubo_range now refers to the final
binding table index, we need to adjust it before using to index
shs->constbuf.

Jason pointed out that we don't need to keep an entire copy of the
serialized NIR around, we just need the SHA1. This does change our
disk cache key to be taking a SHA1 of a SHA1, which is a bit odd,
but should work out and be faster and use less memory.

This implements storing and retrieving iris_compiled_shader objects
from the on-disk shader cache.

This creates the on-disk shader cache data structure, and handles the
build-id keying aspects. The next commits will fill it out so it's
actually used.
