Emma Anholt d76fb3b2b1 glsl/opt_algebraic: Drop the flrp recognizer. 
No change to r300.

freedreno looks mixed but slightly positive in instructions:

total instructions in shared programs: 11012472 -> 11012453 (<.01%)
instructions in affected programs: 8250 -> 8231 (-0.23%)

Emma Anholt 579aca894f glsl/opt_algebraic: Drop the ftrunc pattern recognizer. 
Now that it's in NIR, there's no change to r300 or freedreno shader-db
when we do.

It's not connected up to anything at the moment, and even if I do enable

Emma Anholt 8c4b88ee48 gallium+glsl: Remove EmitNoSat/PIPE_CAP_VERTEX_SHADER_SATURATE

- nv30, which gets lowering using NIR's lower_fsat flag.
- r300, which gets lowering using NIR's lower_fsat flag.
- a2xx, which has was getting it optimized back to fsat anyway.

This drops the check for the cap from gallium nine.  While nine does have
a non-nir path, I think it's safe to assume that if you have SM3
texturing, you can do fsat.

Marcin Ślusarz 89bc8ff408 glsl/opt_algebraic: disable invalid optimization 
When operators other than eq and ne are involved we can't really
move operands around and negate them because such transformation
may change the value of the whole expression.

Some examples:

For unsigned var:
0 >= 1u + var would eventually become 0xffffffff >= var,
which would always evaluate to true, when original expression
was true only for var == 0xffffffff.

For signed var:
0 >= 1 + var would become -1 >= var, which would evaluate to
false for var == 2147483647, when original expression evaluated
to true (because signed overflow is defined to wrap around in
glsl, 1 + 2147483647 == -2147483648, so 0 >= -2147483648).

Timothy Arceri 77f5221233 glsl: pass mem_ctx to constant_expression_value(...) and friends 
The main motivation for this is that threaded compilation can fall
over if we were to allocate IR inside constant_expression_value()
when calling it on a builtin. This is because builtins are shared
across the whole OpenGL context.

f81ede4699 worked around the problem by cloning the entire
builtin before constant_expression_value() could be called on
it. However cloning the whole function each time we referenced
it lead to a significant reduction in the GLSL IR compiler
performance. This change along with the following patch
helps fix that performance regression.

Other advantages are that we reduce the number of calls to
ralloc_parent(), and for loop unrolling we free constants after
they are used rather than leaving them hanging around.

Timothy Arceri e2e2c5abd2 glsl: calculate number of operands in an expression once 
Extra validation is added to ir_validate to make sure this is
always updated to the correct numer of operands, as passes like
lower_instructions modify the instructions directly rather then
generating a new one.

The reduction in time is so small that it is not really
measurable. However callgrind was reporting this function as
being called just under 34 million times while compiling the
Deus Ex shaders (just pre-linking was profiled) with 0.20%
spent in this function.

v2:
 - make num_operands a unit8_t
 - fix unsigned/signed mismatches
