ir_to_mesa: Remove sat to clamp lowering pass

Fixes an infinite loop in swrast where the lowering pass unpacks saturate into
clamp but the opt_algebraic pass tries to do the opposite.

v3 (Ian):
This is a revert of commit cfa8c1cb "ir_to_mesa: lower ir_unop_saturate" on
the ir_to_mesa.cpp portion. prog_execute.c can handle saturates in vertex
shaders, so classic swrast shouldn't need this lowering pass.

Multiple scenes per context are meant to be used so a new scene can be built

this does not actually work (and according to git log, possibly never did,
though maybe it did at some point further back (5 years+) but was buggy)
because we always wait immediately on the rasterizer to finish the scene when
contexts (and hence setup/scene) is flushed. This means when we try to get
an empty scene later, any old one is already empty again.
Thus using multiple scenes is just a waste of memory (not too bad, since the
additional scenes are guaranteed to be empty, which means their size ought to
be one data block (64kB) plus the size of some structs), without actually

i965: Compute VS attribute WA bits earlier and check if they changed.

BRW_NEW_VERTICES is flagged every time we draw a primitive.  Having
the brw_vs_prog atom depend on BRW_NEW_VERTICES meant that we had to
compute the VS program key and do a program cache lookup for every
single primitive.  This is painfully expensive.

The workaround bit computation is almost entirely based on the vertex
attribute arrays (brw->vb.inputs[i]), which are set by brw_merge_inputs.
The only thing it uses the VS program for is to see which VS inputs are
actually read.  brw_merge_inputs() happens once per primitive, and can
safely look at the currently bound vertex program, as it doesn't change
in the middle of a draw.

This patch moves the workaround bit computation to brw_merge_inputs(),
right after assigning brw->vb.inputs[i], and stores the previous WA bit
values in the context.  If they've actually changed from the last draw
(which is uncommon), we signal that we need a new vertex program,
causing brw_vs_prog to compute a new key.

Improves performance in Gl32Batch7 by 13.6123% +/- 0.739652% (n=166)
on Haswell GT3e.  I'm told Baytrail shows similar gains.

v2: Introduce a new BRW_NEW_VS_ATTRIB_WORKAROUNDS dirty bit, rather
    than reusing BRW_NEW_VERTEX_PROGRAM (suggested by Chris Forbes).

source language.

Previously, our code to determine which mode we wanted was duplicated
in 8 different places (VS and FS for Gen4-5, Gen6, Gen7, and Gen8).
The ctx->_Shader->CurrentProgram[stage] == NULL check was confusing
as well - we use CurrentProgram (non-derived state), but _Shader
(derived state).  It also relies on knowing that ARB programs don't
use gl_shader_program structures today.  The compiler already makes
this assumption in a few places, but I'd rather keep that assumption
out of the state upload code.

With this patch, we select the mode at compile time, and store that
choice in prog_data.  The state upload code simply uses that decision.

i965/skl: Fix SBE state upload code.

The state upload code was incorrectly shifting the attribute swizzles. The
effect of this is we're likely to get the default swizzle values, which disables
the component.

This doesn't technically fix any bugs since Skylake support is still disabled by
default (no PCI IDs).

While here, since VARYING_SLOT_MAX can be greater than the number of attributes
we have available, add a warning to the code to make sure we never do the wrong
thing (and hopefully prevent further static analysis from finding this).
Admittedly I am a bit confused. It seems to me like the moment a user has
greater than 8 varyings we will hit this condition. CC Ken to clarify.
