There's no point in performing depth writes when the depth test
comparison function is set to GL_EQUAL - it would just write out
the same value that's already there (if it is written at all). While
this is harmless from a functional perspective, it hurts performance.
Obviously, writing to memory is not free, but there's another more
subtle impact as well: it can prevent early depth optimizations.
Depth writes aren't supposed to happen for pixels that are killed
by fragment shader discard statements or the alpha test. So, with
depth writes enabled and either of those, the pixel shader must be
invoked to determine whether or not to perform the write. This is
fairly stupid in the EQUAL case - we're running a shader to decide
whether to replace the existing depth value with itself.
By disabling these pointless writes, we allow early depth even with
discards and alpha testing, allowing the hardware to skip the pixel
shader altogether if the depth test fails.

Huge thanks to Mark Janes for building frameretrace [1], the performance
analysis tool that helped us find this issue, and to Robert Bragg for
providing us performance metrics on Linux. Mark also spent the time to
analyze Valley performance on Windows vs. Linux and discovered a
discrepancy in early depth test metrics. Once he had isolated a draw
call and drawn attention to the problem, fixing it was pretty simple.

Framebuffer attachments can be specified through FramebufferTexture*
calls. Upon specifying a depth (or stencil) framebuffer attachment that
internally reuses a texture, the cube map face of the new attachment
would not be updated (defaulting to TEXTURE_CUBE_MAP_POSITIVE_X).
Fix this issue by actually updating the CubeMapFace field.
This bug manifested itself in BindFramebuffer calls performed on
framebuffers whose stencil attachments internally reused a depth
texture. When binding a framebuffer, we walk through the framebuffer's
attachments and update each one's corresponding gl_renderbuffer. Since
the framebuffer's depth and stencil attachments may share a
gl_renderbuffer and the walk visits the stencil attachment after
the depth attachment, the uninitialized CubeMapFace forced rendering
to TEXTURE_CUBE_MAP_POSITIVE_X.

Instead of doing all the math with scalars, use vectors. This means the
overflow math needs to be done manually, albeit that's only really
problematic for the stride/index mul, the rest has been pretty much
moved outside the shader loop (albeit the mul could actually be optimized
away too), where things are still scalar.
To eliminate control flow in the main shader loop fetch, provide fake
buffers (so index 0 is always valid to fetch).
Still uses aos fetch though in the end - mostly because some more code
would be needed to handle unaligned fetches in that path, and because for
most formats it won't make a difference anyway (we generate some truly
horrendous code for things like R16G16_something for instance).
Instanced fetch however stays roughly the same as before, except that
no longer the same element is fetched multiple times (I've seen a reduction
of ~3 times in main shader loop size due to llvm not recognizing it's all
the same fetch, since it would have been possible some of the fetches
getting replaced with zeros in case vector size exceeds remaining fetch
count - the values of such fetches don't matter at all though).
Also, for elts gathering, use vectorized code as well.
The generated shaders are smaller and faster to compile (not entirely sure
about execution speed, but generally unless there's just single vertices
to handle I would expect it to be faster - there's more opportunities
for future improvements by using soa fetch).
v3: skip the fake index buffer, not needed due to the jit code never seeing
the real index buffer in the first place.
Fix a bug with mask expansion (needs SExt, not ZExt).
Also, be really really careful to keep the behavior the same, even in cases
where it looks wrong, and add comments why the code is doing the seemingly
wrong stuff... Fortunately it's not actually more complex in the end...
Also change function order slightly just to make the diff more readable.

If the filename exceeds an OS path limit, presumably fopen() will

This commit adds basic support for color compression. For the moment,
color compression is only enabled within a render pass and a full resolve
is done before the render pass finishes. All texturing operations still
happen with CCS disabled.
