Jonathan Marek ee1ed59458 etnaviv: prep for UBOs
Allow UBO relocs and only emitting uniforms that are actually used.

GC7000Lite has no address register, so upload uniforms to a UBO object to
LOAD from.

I removed the code to check for changes to individual uniforms and just
reupload to entire uniform state when the state is dirty. I think there
was very limited benefit to it and it isn't compatible with relocs.

The LIMA_DEBUG=shaderdb setting can be useful to output stats on
applications other than shader-db.

Ian Romanick 5544b2cbbd nir/algebraic: Use value range analysis to eliminate useless unary ops
Sandy Bridge is the big winner because it lies at something of a
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
shaders can run on it.  The old style math box means extra moves are
necessary to resolve source modifiers on operands to complex math
instructions like COS, SQRT, and RCP.

v2: Remove a couple patterns that are now redundant.

Ian Romanick 96fcb3f95b 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.

Ian Romanick 405de7ccb6 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.
