The spec doesn't actually mention adding this, but this is the usual
pattern so I'm assuming it's a spec bug.

When the last context in a share group is destroyed, the hash table
containing all of the shader programs (ctx->Shared->ShaderObjects) is
destroyed, throwing away all of the shader programs.
Using a static variable to store program IDs ends up holding on to them
after this, so we think we still have a compiled program, when it
actually got destroyed. _mesa_UseProgram then hits GL errors, since no
program by that ID exists.
Instead, store the program IDs in the context, so we know to recompile
if our context gets destroyed and the application creates another one.
Fixes es3conform tests when run without -minfmt (where it creates
separate contexts for testing each visual).

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.

Acording to the OpenCL spec, it is possible to have a buffer mapped
for reading and at read from it using commands or buffers.
With this we can keep the mapping (that exists against the
temporary item) and read with a kernel (from the item we have
just added to the pool) without problems.

This patch changes completely the way buffers are added to the
compute_memory_pool. Before this, whenever we were going to
map a buffer or write to or read from it, it would get placed
into the pool. Now, every unallocated buffer has its own
r600_resource until it is allocated in the pool.
NOTE: This patch also increase the GPU memory usage at the moment
of putting every buffer in it's place. More or less, the memory
usage is ~2x(sum of every buffer size)

The intention of this pass was to give us better instruction scheduling
opportunities, but it unexpectedly reduced some instruction counts as
well:
total instructions in shared programs: 1666639 -> 1666073 (-0.03%)
instructions in affected programs: 54612 -> 54046 (-1.04%)
(and trades 4 SIMD16 programs in SS3)
Previously llvm detected cpu features automatically when the execution engine
was created (based on host cpu). This is no longer the case, which meant llvm
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
despite at least some llvm versions enabling it anyway we always set this
manually). So, instead of trying to figure out which MAttrs to set just set
MCPU.
