With the exception of always-taken switch cases (which are
indistinguishable from straight line code in our IR), this
disallows use of the builtin barrier() function in all the
places it may not appear.

Tessellation control outputs can be read in directly without first
having been written. Accessing these will require some special logic
anyways, so just let them through.
V2: Never lower tess control output reads, whether patch or not -- both
can be read back by other threads.

This is technically not needed, but it makes the compiler return a better
error message if tessellation is used with GLSL < 1.50.
Instead of:
error: syntax error, unexpected NEW_IDENTIFIER, expecting $end
It returns:
error: #version 150 layout qualifier `triangles' used
And the tessellation spec says:
OpenGL 3.2 and GLSL 1.50 are required.
So it makes perfect sense.

This is done by returning an rvalue of type void in the
ast_function_expression::hir function instead of a void expression.
This produces (in the case of the ternary) an hir with a call
to the void returning function and an assignment of a void variable
which will be optimized out (the assignment) during the optimization
pass.
This fix results in having a valid subexpression in the many
different cases where the subexpressions are functions whose
return values are void.
Thus preventing to dereference NULL in the following cases:
* binary operator
* unary operators
* ternary operator
* comparison operators (except equal and nequal operator)
Equal and nequal had to be handled as a special case because
instead of segfaulting on a forbidden syntax it was now accepting
expressions with a void return value on either (or both) side of
the expression.

Since the backing storage for these is shared we cannot ensure that
the value won't change by writes from other threads. Normally SSBO
accesses are not guaranteed to be syncronized with other threads,
except when memoryBarrier is used. So, we might be able to optimize
some SSBO accesses, but for now we always take the safe path and emit
the SSBO access.

If we kill dead assignments we lose the buffer writes.
Also, we never kill UBO declarations even if they are never referenced
by the shader, they are always considered active. Although the spec
does not seem say this specifically for SSBOs, it is probably implied
since SSBOs are pretty much the same as UBOs, only that you can write
to them.

This will be used to identify buffer variables inside shader storage
buffer objects, which are very similar to uniforms except for a few
differences, most important of which is that they are writable.
Since buffer variables are so similar to uniforms, we will almost always
want them to go through the same paths as uniforms.
