But in the cases where the user creates a buffer to act as an

nv50/ir: allow gl_ViewportIndex to work on non-provoking vertices

Previously, if we had something like:

  for(int i = 0; i < gl_in.length(); i++) {
     gl_Position = gl_in[i].gl_Position;
     EmitVertex();
  }
  EndPrimitive();

The right viewport index would not be set on the primitive because the
last vertex is the provoking one. However blob drivers appear to move
the gl_ViewportIndex write into the for loop, allowing the application
to be ignorant of this detail.

While the application is technically wrong here, because the blob does
it and other drivers appear to implicitly work this way as well, we add
a buffer register that viewport index writes go into, which is then
exported before every EmitVertex() call.

i965: Allow the blorp blit between BGR and RGB

Previously the blorp blitter would only be used if the format is identical or
there is only a difference between whether there is an alpha component or not.
This patch makes it also allow the blorp blitter if the only difference is the
ordering of the RGB components (ie, RGB or BGR).

This is particularly useful since commit 61e264f4fcdba3623 because Mesa now
prefers RGB ordering for textures but the window system buffers are still
created as BGR. That means that the blorp blitter won't be used for the
(probably) common case of blitting from a texture to the window system buffer.

This doesn't cause any regressions in the FBO piglit tests on Haswell. On
Sandybridge it causes the fbo-blit-stretch test to fail but that is only
because it was failing anyway before the above commit and that commit hid the
problem.

glx: Don't crash on swap event for a Window (non-GLXWindow)

Prior to GLX 1.3 there was the glxMakeCurrent() function that took a
single drawable handle. The Drawable could be either a bare XID for a
Window or an XID for a glxpixmap.

GLX 1.3 added glxMakeContextCurrent that takes 2 handles: one for
reading, one for writing. Nowadays the old glxMakeCurrent call is
implemented as a call to glxMakeContextCurrent with the single handle
duplicated.

Because of this it is allowed to use a plain-old Window ID as an
argument to glxMakeContextCurrent, although nobody really documents this
sort of thing. The manpage for the NEW call specifies the arguments as
GLXPixmaps, but the actual code accepts Window XIDs too, and handles
them correctly.

Similarly, the glxSelectEvents function can also take a bare Window XID.

The "piglit" tests all use GLXWindows and/or GLXPixmaps. You never
tested swap events with a bare Window XID. That is what my app was
doing.

The swap_events code worked with Window XIDs in mesa 7.x.y. The new code
added in versions 8, 9, and 10 assumes that all buffer swap events have
a GLXPixmap associated with them. Because of the historical quirks
above, this is not true. Swap events for bare Window XIDs do NOT have a
glxpixmap resulting in a segfault.

Any app that uses the old school glxMakeCurrent call with a Window XID
while trying to use swap_events will crash when the libs try to lookup
the nonexistent GLXPixmap associated with the incoming swap event.

I believe that the people who wrote the spec overlooked this, because
the "sbc" field comes from the OML_sync extension that is defined in
terms of glxpixmaps only.

Previously llvm detected cpu features automatically when the execution engine

was then not able to emit some of the intrinsics we used as we didn't specify
any sse attributes (only on avx supporting systems this was not a problem since

manually). So, instead of trying to figure out which MAttrs to set just set
MCPU.
