This is the same change as the previous commit to the FS.  A very few VSes
are regressed by 1 or 2 instructions, which look recoverable with a bit
more dead code elimination.

Reviewed-by: Ian Romanick <ian.d.romanick@intel.com>

Previously, we would sometimes not consider a write to a register to
extend the end of the interval, nor would we consider a read before a
write to extend the start.  This made for a bunch of complicated logic
related to how to treat the results when dead code might be present.
Instead, just extend the interval and fix dead code elimination to know
how to remove it.

Interestingly, this actually results in a tiny bit more optimization:
total instructions in shared programs: 1391220 -> 1390799 (-0.03%)
instructions in affected programs:     14037 -> 13616 (-3.00%)

v2: Fix a theoretical problem with the simd16 workaround if dst == src,

Updated ilo_draw_vbo to be able to check that the indexed

[olv: a minor fix after rebasing and formatting]

Before, if we failed to allocate the index buffer we'd silently
return from st_draw_vbo() without drawing anything.  We should
raise GL_OUT_OF_MEMORY to give some indication that something went
wrong.

It is decompressed to and stored as PIPE_FORMAT_R8G8B8X8_UNORM on-the-fly.

It can be used for unpacking compressed texture on-the-fly or to support
explicit transfer flushing.

We want to or need to use a different mapping method when when the resource is
busy, the bo format differs from the requested format, and etc.

For separate stencil buffer or formats not supported natively, the real format
of the bo may differ from that requested.

It helps a bit with vertex shader performance on i915g
(a couple percent faster with openarena).

I have tried most other passes, and they weren't showing
any measurable improvement. Note that my vertex shaders
didn't have loops, so maybe the loop optimizations could
still be useful in the future.

This basically reverts commit
2acc719374.

With the previous change, we're not batchbuffer limited any
longer. So we actually start seeing a performance difference
between X and Y tiling. X tiling is funny because it is
faster for screen-aligned quads but slower in games. So let's
use Y tiling which is 10% faster overall.

Now that we don't throttle at every batchbuffer, we can shrink
the size of batchbuffers to achieve early flushing. This gives
a significant speed boost in a lot of games (on the order of
20%).

There is a subtle difference with this change.  When TXP is used with an array
