This way we get correct sampling from RGB formats that are faked as RGBA.
This should also cause it to disable rendering and blending on those
formats. We should be able to render to them and, on Broadwell and above,
we can blend on them with work-arounds. However, we'll add support for
that more properly later when it's deemed useful. For now, disabling
rendering and blending should be safe.
The new code removes the switch statement and instead handles depth/stencil
as up-front special cases. This allows for potentially more complicated
color format handling in the future.
This commit removes anv_format_for_vk_format and adds an anv_get_format
helper. The anv_get_format helper returns the anv_format by-value. Unlike
anv_format_for_vk_format the format returned by anv_get_format is 100%
accurate and includes any tweaks needed for tiled vs. linear.
anv_get_isl_format is now just a wrapper around anv_get_format that picks
off just the isl_format.
Now that we have VkFormat introspection and we've removed everything that
tried to use anv_format for introspection, we no longer need most of what
was in anv_format.
Fixes some failures in dEQP-VK.api.info.image_format_properties.* and
enables the test group to execute without assert failing.
