2ea923cf571235dfe573c35c3f0d90f632bd86d8 had the side effect of IR counting
now being done after IR optimization instead of before. Some quick analysis
shows that there's roughly 1.5 times more IR instructions before optimization
than after, hence the effective shader cache size got quite a bit smaller.
Could counter this with an increase of the instruction limit but it probably
makes more sense to count them after optimizations, so move that code.

We already have a perfectly good copy of the program key, and nobody is
going to modify it. The only reason we copied it was because the
brw_wm_compile structure embedded the key rather than pointing to it.

'c' is going away, but we still need a memory context that lives
for the duration of the compile.

Previously, the memory context situation was a bit of a mess:
fs_visitor allocated its own memory context, and freed it in the
destructor. However, some data produced by fs_visitor (such as the list
of instructions) needs to live beyond when fs_visitor is "done", so the
caller can pass it to fs_generator.
Everything worked out because brw_wm_fs_emit's fs_visitor variables
happen to not go out of scope until the end of the function. But that
meant that moving the declaration of, say, the SIMD16 fs_visitor
instance, could cause everything to explode.
Using a memory context that exists for the duration of the compile is
clearer, and should be equivalent.
Ultimately, we don't want to use 'c', but this matches the behavior of
fs_generator and gen8_fs_generator, so it'll be simple to change later.

runtime_check_aads_emit isn't actually used currently, but I believe

This data is created by fs_visitor and only used when emitting code,
so keeping it in fs_visitor makes sense. I decided it would be
reasonable to group these all together in a struct, since they're
highly related.

As far as I can tell, there's no point in allocating an extra register
and generating a MOV---we can just use the copy provided as part of our
thread payload directly. It's already in the right format.
Of course, there are zero Piglit tests for this. We don't actually ship
the extension (GL_ARB_gpu_shader5) that exposes this functionality
either.

With this one use gone, c->last_scratch is now only used inside
fs_visitor. The rest of the driver uses prog_data->total_scratch.
We already compute similar prog_data fields in fs_visitor, so this

The if (!allocated_without_spills) block is an obvious spot for this
performance warning message.
In the Vec4 backend, scratch is also used for indirect access of
temporary arrays. The FS backend doesn't implement that yet, but
if it did, this message would be inaccurate, since scratch access
wouldn't necessarily mean spilling. Moving it preemptively fixes that.

Looping over the instructions and calling brw_disasm doesn't handle
compacted instructions. In most cases, this hasn't been a problem since
we don't compact prior to Sandybridge.
However, Sandybridge's transform feedback GS program should already be
compacted, and so this ought to fix decoding of that.

UNION appears to expect that all of its sources are conditionally
defined. Otherwise it inserts an unpredicated mov instruction which
overwrites the desired result. This fixes tests that use UMUL_HI, and
much less directly, unsigned integer division by a constant, which uses
this functionality in a peephole pass.

Enabled with GALLIVM_DEBUG=perf (which up to now was only used to print
warnings for unoptimized code).
While some unexpectedly long shader compile times for some shaders were fixed
with 8a9f5ecdb116d0449d63f7b94efbfa8b205d826f this should help recognize such
problems in the future. For now though only available in debug builds (which
are not always suitable for such analysis). And since this uses system time,
it might not be all that accurate (even llvmpipe's own rasterization threads
might be running at the same time, or just other tasks).
(llvmpipe also has LP_DEBUG=counters but this only gives an average per shader
and the the total time for all shaders.)
This prints information like this:
optimizing module fs17_variant0 took 1 msec
optimizing module setup_variant_0 took 0 msec
optimizing module draw_llvm_vs_variant0 took 9 msec
optimizing module draw_llvm_vs_variant0 took 12 msec
optimizing module fs17_variant1 took 2 msec
v2: rebase for recent gallivm compilation changes, and print time for whole
modules instead of functions (otherwise it would be very spammy since it would
include all trivial inline sse2 functions), using the shiny new module names,
prying them off LLVM using new helper (not available through C bindings).
Per function timings, while possibly giving more information (if there'd be
a problem only in for instance the partial not the whole function), don't seem
all that useful for now.

We allocate dispatch tables for BeginEnd and OutsideBeginEnd. But
when we destroy the context we were freeing the BeginEnd and Exec
tables. If Exec==BeginEnd we did a double-free. This would happen
if the context was destroyed while inside a glBegin/End pair. Now
free the BeginEnd and OutsideBeginEnd pointers.

This workaround doesn't list any llvm version, but it was introduced
2010-06-10 (e277d5c1f6b2c5a6d202561e67d2b6821a69ecc4). It is unlikely
this bug is still present in llvm versions we support (3.1+).
There's no specific test listed, but I ran lp_test_arit (which uses
the mentioned functions) on llvm 3.1 and 3.3 with sse41 disabled and
this pass enabled without issues.

32bit code generation and llvm >= 2.7 used a different optimization pass
order - this code was initially introduced (2010-07-23) by
815e79e72c1f4aa849c0ee6103621685b678bc9d, apparently due to buggy code being
generated with then brand new llvm versions (which was llvm 2.7 plus pre 2.8
devel).
It seems very highly likely that whatever this bug was it has been fixed in
newer llvm versions, though there's no easy way to test this - the mentioned
piglit test has been removed years ago, and even if you'd build it I'm
sceptical the glsl compiler would still produce the required code to trigger
it.
I have no idea what a good order of passes is, but just remove the workaround
and use the same order everywhere.
