- Fix commit title (Jordan Justen)
v2 (Jason Ekstrand):

- Handle the power-of-two limitation for _imm versions
- Add tests

This command allows programming custom pixel hashing tables
controlling the balancing of load across pixel pipes. Rather
confusingly 3DSTATE_SLICE_TABLE_STATE_POINTERS was serving the same
purpose on Gen11: A pixel is mapped to the pixel pipe with index
specified by the entry in the table corresponding to the LSBs of the
pixel coordinates [Yes you read right the entries are neither subslice
nor slice indices!]. Either a 2-way or a 3-way table can be
programmed based on whether the platform has two or three pixel pipes
per slice. In addition the 16x8 tables defined below can hold two
separate 8x8 tables when in DUAL_TABLE mode (which AFAIA is only
useful for platforms with multiple asymmetric slices -- I.e. no
production platforms as of today to my knowledge).

The former "Subslice Hashing Mode" field is no longer used by the
hardware, Gen12 parts always do 16x16 subslice pixel hashing -- Remove
it since it's no longer useful. In addition add a couple of bits that
will be useful in order to make some adjustments to the default pixel
pipe hashing behavior.
