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.

Now we will have a list with the items that are in the pool
(item_list) and the items that are outside it (unallocated_list)
Reviewed-by: Tom Stellard <thomas.stellard@amd.com>
These statuses will help track whether the items are mapped
or if they should be promoted to or demoted from the pool
v2: Use the new is_item_in_pool util function,

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)
v2: Cleanup
v3: Use temporary variables to avoid so many castings in functions,
as suggested by Tom Stellard

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.
This fixes https://bugs.freedesktop.org/show_bug.cgi?id=77493.

This is just a hack, it should be possible to create a temporary zeta
surface and render to that instead. However that's more complicated and
this avoids the render being entirely broken and errors being reported
by the card.

It was set to pipe_resource::last_level and _MaxLevel was embedded in max_lod,
that's why it worked for ordinary texturing. However, min_lod doesn't have
any effect on texelFetch and textureQueryLevels, so we must still set
last_level correctly.

Commit c1c1cf5f9 added infrastructure for saving and restoring draw
buffer state. However, it universially used MAX_DRAW_BUFFERS, but many
drivers support far fewer than that at limit. For example, the radeon
and i915 drivers only support 1. Using MAX_DRAW_BUFFERS causes meta to
generate GL errors.

Such conversions (which are most likely rather pointless in practice) were
resulting in shifts with negative shift counts and shifts with counts the same
as the bit width. This was always undefined in llvm, the code generated was
rather horrendous but happened to work.
So make sure such shifts are filtered out and replaced with something that
works (the generated code is still just as horrendous as before).
This fixes lp_test_format, https://bugs.freedesktop.org/show_bug.cgi?id=73846.
v2: prettify by using build context shift helpers.

A drawable size of 0x0 means that we don't have buffers for a drawable yet,
not that we have a zero-sized buffer. Core mesa shouldn't be optimizing out
drawing based on buffer size, since the draw call could be what triggers
the driver to go and get buffers. As discussed in the referenced bug report,
the optimization was added as part of a scatter-shot attempt to fix a
different problem. There's no other example in mesa core of using the
buffer size in this way.
