nir/algebraic: Use "uint" instead of "unsigned" for uint types
This is consistent with the rename done for the rest of NIR. Currently,
"bool" is the only type specifier used in nir_opt_algebraic.py so this is
really a no-op.

nir/algebraic: Do better error reporting of bad expressions
Previously, if an exception was encountered anywhere, nir_algebraic would
just die in a fire with no indication whatsoever as to where the actual bug
is. This commit makes it print out the particular search-and-replace
expression that is causing problems along with the exception. Also, it
will now report all of the errors it finds and then exit at the end like a
standard C compiler would do.

i965/blorp/gen8: Fix blitting of interleaved msaa surfaces
Fixes ES31-CTS.gtf.GL31Tests.texture_stencil8.texture_stencil8_multisample.
Current logic divides given layer of one by number of samples (four)
trashing the layer to zero. Layer adjustment is only to be used with
non-interleaved msaa surfaces where samples for particular layer are
in multiple slices.
I copy-pasted a bit of documentation from
brw_blorp.c::brw_blorp_compute_tile_offsets().
Also took the opportunity to fix the comment regarding sampling
as 2D, cube textures are the only exception.

A semantic error was introduced in a past refactoring that caused the bind
parameter to be passed into the use_reusable_pool parameter of buffer_create.
Since this clearly makes no sense, and there is no clear reason why the
cache _shouldn't_ be used, just use the cache always.

The llvm TGSI backend uses pointers in registers and does things

i965/fs: Reduce the response length of sampler messages on Skylake.
Often, we don't need a full 4 channels worth of data from the sampler.
For example, depth comparisons and red textures only return one value.
To handle this, the sampler message header contains a mask which can
be used to disable channels, and reduce the message length (in SIMD16
mode on all hardware, and SIMD8 mode on Broadwell and later).
We've never used it before, since it required setting up a message
header. This meant trading a smaller response length for a larger
message length and additional MOVs to set it up.
However, Skylake introduces a terrific new feature: for headerless
messages, you can simply reduce the response length, and it makes
the implicit header contain an appropriate mask. So to read only
RG, you would simply set the message length to 2 or 4 (SIMD8/16).
This means we can finally take advantage of this at no cost.
