95ded68984 glsl/drirc: add an option for gl_ClipVertex / gl_CullDistance checks 
The GLSL spec says it's an error if a shader statically writes to these
2 variables.

Until this commit, Mesa refused to link a shader if it had an unused
function writing to one of these variables while another (used) function
wrote to the other.

This commit adds an option to perform dead function elimination after
the intra-stage linking step but before performing these checks.

d3b72d49cb glsl: Assert that lower_blend_equation_advanced is only called for FS 
It only makes sense to call this pass for fragment shaders, and the
first thing the pass does is read a FS-specific field out of a union,
so it isn't safe to call it for other shader stages.

We could make it early return, but instead we just assert, so that
drivers know to only call it when appropriate.

asserting, was Reviewed-by: Emma Anholt <emma@anholt.net> as well.)

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).

c3f47f6e30 glsl: Properly handle .length() of an unsized array 
There are two distinct cases:
- The last member of a shader storage block (length determined at run-time)
- Implicitly-sized array (length determined at link-time)

Fixes: 273f61a005 ("glsl: Add parser/compiler support for unsized array's length()")

441826aaaa glsl: Add operator for .length() method on implicitly-sized arrays 
ARB_shader_storage_buffer_object extension (promoted to core in 4.3) allows us
to call .length() method on arrays declared without an explicit size. The length is
determined at link time as a maximum array access.
