the patchlist. We can easily create a set to store all the required
curbe registers, and then latter at register allocation stage, we
can easily insert the registers in that set without any other checking.

This way, at register allocation stage, we don't need to know anything
about those CURBE magic number. We only need to use the virtual register
as key naturally. This make the code a little bit clearer.

And most important, this change is to support dynamic curbe register
allocation. For example, the image attributes. Each image may have 6 DWs,
and we may have many images but only access part of the image and part
of the image attributes. So we can't just simply allocate a special
register for all the image attributes. We need to dynamic allocate
curbe registers on demand. So the previous implementation is not

GBE/Runtime: implement workaround for IVB sampler bug

Per IVB spec,

If the surface format of the associated surface is UINT or SINT,
the Surface Type cannot be SURFTYPE_3D or SURFTYPE_CUBE and Address
Control Mode cannot be CLAMP_BORDER or HALF_BORDER.

Besides this bug, there is another undocumented issue. If a surface
data type is IEEE float. Then when we use sampler to sample the pixel,
if the value is betweeo -1p-20 to 0, the sampler will rounding it to
zero. And this will also bring problem when we are using the clamp mode.

This patch is to workaround the above two hardware issues.
It introduces a new intrinsic get_sampler_info to get a sampler type
at runtime. When calling to read_image, it will check whether it
hits the above two cases. If it hit case 1, then we will force it to
use clamp to edge for those pixels within the box, And for those
pixel out of the box, we manually set the border color. To achieve this
solution, we have to prepare two sampler slot for each CL_ADDRESS_CLAMP
sampler. And the first has slot_1 which is using CL_ADDRESS_CLAMP,
the second use slot_1 + 8. Thus we can only use half of 16 samplers.
Fortunately, 8 samplers comply with the OpenCL's minimal requirement.

If it hits case 2, then we minor a epsilon to the coordinate, and
let it not rounds to zero.

If possible, programer should avoid to use float coordinates and/or int/uint
format image. Otherwise, it will hit the very slow path.

With this workaround, the compiler_copy_image1 can pass now.
