intel/eu/gen12: Set SWSB annotations in hand-crafted assembly.

Reviewers are encouraged to audit the code generation pass
independently for the case I missed some potential data hazard or new
code has been added in the meantime.

v2: Add SYNC instruction to cr0 workaround in brw_float_controls_mode().

v3: Drop likely redundant (and potentially harmful) RegDist SWSB
    annotation from ce0 read in brw_find_live_channel() (Caio).

intel/eu/gen12: Don't set thread control, it's gone.

An effect similar to the one formerly provided by setting thread
control to "switch" can be achieved now by setting a RegDist of 1 on
the SWSB field.

annotations.
