i965: Enable vertex streams up to MAX_VERTEX_STREAMS.

mesa: Enable simultaneous queries on different streams.

It should be possible to query the number of primitives written to each
individual stream by a geometry shader in a single draw call. For that
we need to have up to MAX_VERTEX_STREAM separate query objects.

i965: Implement GL_PRIMITIVES_GENERATED with non-zero streams.

So far we have been using CL_INVOCATION_COUNT to resolve this query but this
is no good with streams, as only stream 0 reaches the clipping stage. Instead
we will use SO_PRIM_STORAGE_NEEDED which can keep track of the primitives sent
to each individual stream.

Since SO_PRIM_STORAGE_NEEDED is related to the SOL stage and according to
ARB_transform_feedback3 we need to be able to query primitives generated in
each stream whether transform feedback is active or not what we do is to
enable the SOL unit even if transform feedback is not active but disable all
output buffers in that case. This effectively disables transform feedback
but permits activation of statistics enabling SO_PRIM_STORAGE_NEEDED even
when transform feedback is not active.

While the official INTEL_swap_event specification says that the drawable
field should contain the GLXDrawable, not the Drawable, the existing
DRI2 code in dri2.c that translates from DRI2_BufferSwapComplete sends out
GLX_BufferSwapComplete with the Drawable's ID, so existing codebases

glsl: Relax combinations of layout qualifiers with other qualifiers.

Previously we disallowed any combination of layout with interpolation,
invariant, or precise qualifiers. There is very little spec guidance on
exactly which combinations should be allowed, but with ARB_sso it's
useful to allow these qualifiers with rendezvous-by-location.

Since it's unclear exactly where the layout qualifier should appear when
combined with other qualifiers, we will allow it anywhere before the
auxiliary storage qualifier.

This allows enough flexibility for all examples I've seen, while keeping
the auxiliary-storage-qualifier / storage-qualifier pair together (as
they are a single qualifier in the spec prior to
ARB_shading_language_420pack)

glsl: Don't convert reductions of ivec to a dot-product

Mesa has an optimization that converts expressions like "v.x + v.y + v.z
+ v.w" into dot(v, 1.0).  And therein lies the rub: the other operand to
the dot-product is always a float... even if the vector is an ivec or
uvec.  This results in an assertion failure in ir_builder.

If the base type of the operand is not float, don't try the
optimization.  Dot-product is not valid on integer data.
