6403efbe74 glsl: Remove ir_binop_greater and ir_binop_lequal expressions
NIR does not have these instructions.  TGSI and Mesa IR both implement
them using < and >=, repsectively.  Removing them deletes a bunch of

them.

v2: Rebase on 2+ years of change... and fix a major bug added in the
rebase.

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.

fa4ebf6b8d glsl: add _mesa_glsl_parse_state object to is_lvalue()
Yes, this is a bit hacky but we don't really have the choice.
Plain GLSL doesn't accept bindless samplers/images as l-values
while it's allowed when ARB_bindless_texture is enabled.

The default NULL parameter is because we can't access the
_mesa_glsl_parse_state object in few places in the compiler.
One is_lvalue(NULL) call is for IR validation but other checks
happen elsewhere, should be safe.

cf52b8cd21 glsl: do not make sampler/image types readonly variables
In plain GLSL, sampler and image types can only be declared
uniform-qualified global variables or 'in' function parameters.

Setting the read_only flag seems quite useless because other
checks will prevent sampler/image variables to be assigned and
also because the flag is not set for atomic_uint types which are
opaque types.

This will also help for ARB_bindless_texture because samplers
and images can be assigned when they are considered bindless.

8c628ab13e glsl: make max array trackers ints and use -1 as base. (v2)
This fixes a bug that breaks cull distances. The problem
is the max array accessors can't tell the difference between
an never accessed unsized array and an accessed at location 0
unsized array. This leads to converting an undeclared unused
gl_ClipDistance inside or outside gl_PerVertex to a size 1
array. However we need to the number of active clip distances
to work out the starting point for the cull distances, and
this offset by one when it's not being used isn't possible
to distinguish from the case were only the first element is
accessed. I tried to use ->used for this, but that doesn't
work when gl_ClipDistance is part of an interface block.

So this changes things so that max_array_access is an int
and initialised to -1. This also allows unsized arrays to
proceed further than that could before, but we really shouldn't
mind as they will get eliminated if nothing uses them later.

For initialised uniforms we no longer change their array
size at runtime, if these are unused they will get eliminated
eventually.

v2: use ralloc_array (Ilia)

18f7c88dd6 glsl: fixed uninitialized pointer
Class "ir_constant" had a bunch of constructors where the pointer member
"array_elements" had not been initialized. This could have lead to unsafe
code if something had tried to write anything to it. This patch fixes
this issue by initializing the pointer to NULL in all the constructors.
This issue was discovered by Coverity.

ac089126b9 glsl/types: Rename sampler_type to sampled_type
It's a bit more descriptive since it is the base type that you get when you
sample from it.  Also, the next commit adds a bare "sampler" type and we
need glsl_type::sampler_type available for a public static member.
