TGSI defines TGSI_SEMANTIC_SAMPLEPOS as a 4-component vector with
Z and W set to 0. However, if we ever try to reach thez and w
compoents, we run into trouble because this is implemented as a
swizzle on gl_SamplePosition instead. And gl_SamplePosition only
has x and y.
It seems that recent versions of mesa does just this, causing
shader-compilation errors during dEQP tests.
This fixes regressions in the following tests:

In 4732489 (shader: do not redeclare built-ins as precise), I confused a
mesa shader-compiler bug with a spec problem. Turns out, redeclaring
built-ins as precise is allowed by the spec, just the same as invariant
variables. And even mesa allows this.
What mesa doesn't currently allow, is to redeclare a variable as *both*
invariant *and* precise. This problem does not extend to new
declarations, where this is already handled correctly.
So, let's avoid emitting both; it's not really needed to emit both, as
they essentially have the same effect (disable reordering), just with
some different usage-semantics. And for the cases we support, these are
effectively the same.

When enabling/disabling GL_BLEND via vrend_blend_enable the context
cached the last state and doesn't call glEnable/glDisable if the state
didn't change. However, when gl(Enable|Disable)IndexedEXT is used with
index 0, then this vrenderer internal state is not updated even though
the corresponding GL state may be changed, and calling vrend_blend_enable
later may not update the actual OpenGL state correctly.
In order to avoid this and to simplify the setting the blend enabled state
remove the caching and always call glEnable/glDisable directly.

In 47387e4 (emit precise keyword), I added code to try to declare
outputs as 'precise' if an instruction flagged as precise wrote to it.
Turns out, redeclaring built-ins as 'precise' isn't allowed, so that bit
was a mistake. And because mesa transforms "invariant" into instructions
with the precise-flag set, we can end up writing to built-ins with the
precise-flag, leading to shaders that doesn't compile correctly.
So let's remove the code that emits the precise-keyword when re-declaring
built-ins.
