This change fixes off-by-one results in corner cases such as
0xffffffff / 0x11111111. For details refer to LLVM bug 46212.

Note we are just handling the index part of the format. This is *not*
the full format, which would include the swizzle (or v7 equivalent) and
the sRGB flag. But in the interest of incremental progress, let's move
this part over first and save on decoding complexity.
To avoid substantial churn from prefixing FORMAT to format names, we
special case the enums to avoid the prefix. This is undesirable but
reduces churn, especially since format handling is slated for an
overhaul soon to accomodate v7

While it is correct for MSAA 4x, it will break for MSAA 8x and 16x, and
it is only dubiously correct for no-MSAA. Drop the mask.

The alpha test is lowered by the frontend so we can drop that unused
code path, and stencil state can be computed at CSO create time to
reduce draw-time complexity.

inputs_read/outputs_written are used for a shader stage to
determine the layout of input and output storage. Adjacent stages must
agree on the layout, so adjacent input/output bitfields must match.
Most of the time, cross-stage optimizations make that happen anyway,
but there are some cases (with special values like clip distances and
point size) where this doesn't happen.

v2: Only advertise AFBC if PAN_MESA_DEBUG=afbc is set. This is to avoid
sharing AFBC buffers as SCANOUT until corresponding kernel bugfixes are
landed. Technically a kernel issue but let's prevent a regression.

There are lots of reasons we might fallback on u-interleaved tiling, but
when we can use AFBC, it's a big win.

Instead of converting back and forth we should stick with fourcc codes
as the canonical layout definition. Furthermore modifiers allow all the
variants of AFBC to be encoded canonically, whereas the previous enum
does not (info about YTR is encoded out of band, for instance).
