isl: Add per-gen format introspection
This is just a copy-and-paste from brw_surface_formats.c. For the supports_vertex_fetch function, we do a bit more work so that it properly handles Bay Trail.

* This is the table of support for surface (texture, renderbuffer, and vertex

|

*
|

* The table is formatted to match the documentation, except that the docs have
|

* this ridiculous mapping of Y[*+~^#&] for "supported on DevWhatever". To put
|

* Y*: 45
|

* Y+: 45 (g45/gm45)
|

* Y~: 50 (gen5)

* Y#: 70 (gen7)

* The abbreviations in the header below are:
|
||||
* smpl - Sampling Engine
|
||||
* filt - Sampling Engine Filtering
|
||||
* shad - Sampling Engine Shadow Map
|
||||
* CK - Sampling Engine Chroma Key
|
||||
* RT - Render Target

* AB - Alpha Blend Render Target
|

* VB - Input Vertex Buffer
|

* SO - Steamed Output Vertex Buffers (transform feedback)
|
||||
* color - Color Processing
|

* ccs_e - Lossless Compression Support (gen9+ only)
|

* sf - Surface Format
|
||||
*
|
||||
* See page 88 of the Sandybridge PRM VOL4_Part1 PDF.
|
||||
*
|
||||
* As of Ivybridge, the columns are no longer in that table and the
|
||||
* information can be found spread across:
|
||||
*
|
||||
* - VOL2_Part1 section 2.5.11 Format Conversion (vertex fetch).
