nir/algebraic: Reassociate add-and-shift to be shift-and-add
...
A common thing in many shaders:
uniform vs { vec4 bones[...]; };
...
x = some_calculation(bones[i + 0]);
y = some_calculation(bones[i + 1]);
z = some_calculation(bones[i + 2]);
This turns into stuff like
vec1 32 ssa_12 = iadd ssa_11, ssa_0
vec1 32 ssa_13 = ishl ssa_12, ssa_3
vec1 32 ssa_14 = intrinsic load_ssbo (ssa_7, ssa_13) (16, 4, 0)
vec1 32 ssa_15 = iadd ssa_11, ssa_1
vec1 32 ssa_16 = ishl ssa_15, ssa_3
vec1 32 ssa_17 = intrinsic load_ssbo (ssa_7, ssa_16) (16, 4, 0)
vec1 32 ssa_18 = iadd ssa_11, ssa_2
vec1 32 ssa_19 = ishl ssa_18, ssa_3
vec1 32 ssa_20 = intrinsic load_ssbo (ssa_7, ssa_19) (16, 4, 0)
By reassociating the shift and the add, we can reduce this to
vec1 32 ssa_12 = ishl ssa_11, ssa_3
vec1 32 ssa_13 = iadd ssa_12, ssa_0
vec1 32 ssa_14 = intrinsic load_ssbo (ssa_7, ssa_13) (16, 4, 0)
vec1 32 ssa_16 = iadd ssa_12, ssa_1
vec1 32 ssa_17 = intrinsic load_ssbo (ssa_7, ssa_16) (16, 4, 0)

nir: add a pass to clamp gl_PointSize to a range

The OpenGL and OpenGL ES specs require that implementations clamp the
value of gl_PointSize to an implementation-depedent range. This pass
is useful for any GPU hardware that doesn't do this automatically
for either one or both sides of the range, such as V3D.
v2:
- Turn into a generic NIR pass (Eric).
- Make the pass work before lower I/O so we can use the deref variable
to inspect if we are writing to gl_PointSize (Eric).
- Make the pass take the range to clamp as parameter and allow it
to clamp to both sides of the range or just one side.
- Make the pass report progress.
v3:
- Fix copyright header (Eric)
- use fmin/fmax instead of bcsel to clamp (Eric)

crossroads. It supports a fairly high OpenGL version, and it still has
the old style math box. The high OpenGL version means a lot more

necessary to resolve source modifiers on operands to complex math
instructions like COS, SQRT, and RCP.

nir/algebraic: Use value range analysis to eliminate tautological compares not used by if-statements
...
This just eliminates tautological / contradictory compares that are used
for bcsel and other non-if-statement cases. If-statements are not
affected because removing flow control can cause the i965 instrution
scheduler to create some very long live ranges resulting in unncessary
spilling. This causes some shaders to fall of a performance cliff.
Since many small if-statements are already flattened to bcsel, this
optimization covers more than 68% of the possible cases (2417 shaders
helped for instructions on Skylake vs. 3554).
v2: Reorder and add whitespace to make the relationship between the
patterns more obvious. Suggested by Caio.

nir/range-analysis: Rudimentary value range analysis pass
...
Most integer operations are omitted because dealing with integer
overflow is hard. There are a few things that could be smarter if there
was a small amount more tracking of ranges of integer types (i.e.,
operands are Boolean, operand values fit in 16 bits, etc.).
The changes to nir_search_helpers.h are included in this patch to
simplify reordering the changes to nir_opt_algebraic.py.
v2: Memoize range analysis results. Without this, some shaders appear
to get stuck in infinite loops.
v3: Rebase on many months of Mesa changes, including 1-bit Boolean
changes.
v4: Rebase on "nir: Drop imov/fmov in favor of one mov instruction".
v5: Use nir_alu_srcs_equal for detecting (a*a). Previously just the SSA
value was compared, and this incorrectly matched (a.x*a.y).
v6: Many code improvements including (but not limited to) better names,
more comments, and better use of helper functions. All suggested by
Caio. Rework the handling of several opcodes to use a table for mapping
source ranges to a result range. This change fixed a bug that caused
fmax(gt_zero, ge_zero) to be incorrectly recognized as ge_zero.
Slightly tighten the range of fmul by recognizing that x*x is gt_zero if
x is gt_zero. Add similar handling for -x*x.
v7: Use _______ in the tables as an alias for unknown. Suggested by
Caio.

When we detect a scalar/vector copy through load_deref/store_deref, we
have to be careful since those can bitcast an int to a float and
vice-versa even though copy_deref can't.

We have a cap bit for gallium and a GLSL compiler flag to control this.
Just trust what GLSL gives us and stop forcing it. In order for this to
be safe, we have to advertise another cap in some of the gallium
