glsl: Generate code for constant ir_binop_lshift and ir_binop_rshift expressions

The code generated is quite different from what was previously used.  I
believe that it is still correct by the GLSL spec, and I believe, due to
C rules about shifts, the behavior will be the same.

Section 5.9 (Expressions) of the GLSL 4.50 spec says:

    The result is undefined if the right operand is negative, or greater
    than or equal to the number of bits in the left expression's base
    type.

anv: Rework pipeline caching

The original pipeline cache the Kristian wrote was based on a now-false
premise that the shaders can be stored in the pipeline cache.  The Vulkan
1.0 spec explicitly states that the pipeline cache object is transiant and
you are allowed to delete it after using it to create a pipeline with no
ill effects.  As nice as Kristian's design was, it doesn't jive with the
expectation provided by the Vulkan spec.

The new pipeline cache uses reference-counted anv_shader_bin objects that
are backed by a large state pool.  The cache itself is just a hash table
mapping keys hashes to anv_shader_bin objects.  This has the added
advantage of removing one more hand-rolled hash table from mesa.

This new anv_shader_bin struct stores the compiled kernel (as an anv_state)
as well as all of the metadata that is generated at shader compile time.
The struct is very similar to the old cache_entry struct except that it
is reference counted and stores the actual pipeline_bind_map.  Similarly to
cache_entry, much of the actual data is floating-size and stored after the
main struct.  Unlike cache_entry, which was storred in GPU-accessable
memory, the storage for anv_shader_bin kernels comes from a state pool.
The struct itself is reference-counted so that it can be used by multiple
pipelines at a time without fear of allocation issues.

i965/blorp: Expose the shader cache through function pointers

This sanitizes blorp's access to the i965 driver's shader cache by patching
it through the blorp_context.  When we start using blorp in Vulkan, we will
simply have to implement such a caching interface in the Vulkan driver.

Note: In my first attempt at this, I simplified it down to a single
upload_shader entrypoint and implemented the caching inside of blorp.  This
doesn't work, however, because the i965 driver will, on occation, dump its
entire cache and start over.  When this happens, blorp needs to be able to
recompile its shaders and re-upload them.  It's easiest to just expose the
caching interface.
