This brings back c9e33e5cbf ("intel/fs/cse: Make HALT instruction act
as CSE barrier."), from the old CSE pass into the new one.
Fixes new CTS test: dEQP-VK.subgroups.shader_quad_control.terminated_invocation
Fixes: 9690bd369d ("intel/brw: Delete old local common subexpression elimination pass")

Now that the brw_ip_ranges analysis is being used, there's no
need to track start_ip/end_ips in the blocks as they are mutate. And
also no need to call adjust_block_ips at the end of some passes.

INSTRUCTION_DATA_FLOW.

We can just specify this as a source to the logical FB read/write
opcodes. Notably FB reads had no sources before; now they have one.

The pass is currently turning this :
mul(16) %17:F, %1:F, 0.5f
mul(16) %19:F, %1:F, -0.5f
(+f0.0) sel(16) %27:UD, %19:UD, %17:UD
into this :
{ 12} mul(16) %17:F, %1:F, 0.5f
{ 14} (+f0.0) sel(16) %27:UD, -%17:F, %17:UD
The type change in the SEL instruction incurs a type conversion that
produces invalid values.
