This adds a few new fields in the brw_cs_prog_data struct and then
uses them to fill in the relevant COMPUTE_WALKER fields.
Although the Tile Layout field theoretically has different settings for
32/64/128bpe, it appears that the recommended programming is to always
pick either TileY 32bpe or Linear. It's not very practical to look at
the surface formats involved, anyway.

We'll want to check for Alchemist and set various prog_data fields
in the next patch, in order to enable some optimizations. Passing
NULL for prog_data will remain valid and continue working as before.

With regards to implicit masking of the shift counts for 8- and 16-bit
types, the PRMs are incorrect. They falsely state that on Gen9+ only the
low bits of src1 matching the size of src0 (e.g., 4-bits for W or UW
src0) are used. The Bspec (backed by data from experimentation) state
that 0x3f is used for Q and UQ types, and 0x1f is used for **all** other
types.
To match the behavior expected for the NIR opcodes, explicit masks for
8- and 16-bit types must be added.
This fixes (the updated version, see crucible!138) of
func.shader.shift.int16_t on all Intel platforms. According to Karol,
this also fixes "integer_ops integer_rotate" tests in OpenCL CTS.

Also, this change takes the Xe2 register width in consideration that

No driver supports urol/uror on all bit sizes. Intel gen11+ only for 16
and 32 bit, Nvidia GV100+ only for 32 bit. Etnaviv can support it on 8,
16 and 32 bit.
Also turn the `lower` into a `has` option as only two drivers actually
support `uror` and `urol` at this momemt.
Fixes crashes with CL integer_rotate on iris and nouveau since we emit

When building the CFG the instructions are taken of the list in
fs_visitor and added to the lists inside each block. The single
"exec_node" in the instruction is used for those memberships.
In the case the pass rebuilt the CFG, it had no instructions, so
calculate_cfg() had nothing to work with. For now fix the bug by
pulling all the instructions back to the original list.
We can do better here, but punting until upcoming work on
CFG itself.
Issue found in an unpublished CTS test. Small reproduction in our

Having the reg set with predication disabled shouldn't cause any problems

be shown in the output, so the recompiling will cause
