We need the intrinsics with offsets, so why not just add them all.
The R128 parameter will also be useful for reducing SGPR usage.
GL_ARB_image_load_store also adds some image GLSL modifiers like "coherent",
so Mesa will probably translate those to slc, glc, etc.
When LLVM 3.5 is released, I'll switch Mesa to these new intrinsics.

This contains all the previous patches + getlod support on top of it.
It doesn't use SDNodes anymore, so it's quite small.
It also adds v16i8 to SReg_128, which is used for the sampler descriptor.

For _XYZ, the type of VDATA is v4i32, because v3i32 doesn't exist.
The ADDR64 bit is not exposed. A simpler intrinsic that doesn't take
a resource descriptor might be nicer.
The maximum number of input SGPRs is bumped to 17.

Now that compute support is better on SI, we can't continue using v16i8
for descriptors since this is also a legal type in OpenCL.
This patch fixes numerous hangs with the piglit OpenCL test and since
we now use a target specific DAG node for LOAD_CONSTANT with the
correct MemOperandFlags, this should also fix:

Handle vectors of 1 to 16 integers.
Change the intrinsic names to prevent the wrong one from being selected at
runtime due to the overloading.

This patch replaces the control flow handling with a new
pass which structurize the graph before transforming it to
machine instruction. This has a couple of different advantages
and currently fixes 20 piglit tests without a single regression.
It is now a general purpose transformation that could be not
only be used for SI/R6xx, but also for other hardware
implementations that use a form of structurized control flow.
