draw/llvm: Remove unused gs_constants from jit_context

The member was never used and we'll need to handle it differently
because gs will also need samplers/textures setup.

draw/gs: Abstract the portions of GS that are tgsi specific

To be able to add llvm paths later on we need to have some common
interface for them.

draw/gs: Fetch more than one primitive per invocation

Allows executing gs on up to 4 primitives at a time. Will also be
required by the llvm code because there we definitely don't want
to flush with just a single primitive.

draw: Allocate the output buffer for output primitives

We were allocating the output buffer but using the input
primitives. We need to allocate that buffer using the
maximum number of output, not input, primitives.

i965: Provide more detailed information to match shader_time to programs.

Ken asked me the other day what -1 vs 0 vs 3 vs other meant in our shader
names, and I realized that it was really unclear.  I'd like to do even
better, like noting which one is the clear shader, but that would require
exposing the metaops struct to the driver.

i965/fs: Switch shader_time writes to using GRFs.

This avoids conflicts between shader_time and FB writes, so we can include
more of the program under our profiling.  This does mean hiding more of
the message setup from the optimizer, which doesn't have a way to handle
multi-reg sends from GRFs.

i965/fs: Include everything but the final FB write in shader_time.

Previously, if you just wrote a constant color to the render target, no
time got noted at all.  This is convenient for doing single-instruction
timings, but not so much for actual program analysis.
