glsl: Add check for unsized arrays to glsl types

The main purpose of this patch is to increase readability of
the array code by introducing is_unsized_array() to glsl_types.
Some redundent is_array() checks are also removed, and small number
of other related clean ups.

The introduction of is_unsized_array() should also make the
ARB_arrays_of_arrays code simpler and more readable when it arrives.

V2: Also replace code that checks for unsized arrays directly with the
length variable

i965: Do not set bilinear_filter flag in case of multisample blits

Setting bilinear_filter flag in case of multisample blits with
GL_LINEAR filter causes incorrect behavior in translate_dst_to_src()
function. This broke Modern Warfare (1, 2 and 3) on SNB, IVB and HSW.

Tested on SNB and IVB, no Piglit regressions. Trace file of the game
(taken with apitrace) works fine with this patch.

i965: CS writes/reads should use I915_GEM_INSTRUCTION

Otherwise the gen6 w/a in the kernel won't kick in and the write will
land nowhere.

Inspired by a patch Ken pointed me at which had the same issue (but
isn't yet merged and also for a gen7+ feature). An audit of the entire
driver didn't reveal any other case than the one in in the write_reg
helper used by the gen6 queryobj code.

i965: Emit post-sync non-zero flush before 3DSTATE_GS_SVB_INDEX.

From the comments above intel_emit_post_sync_nonzero_flush:
"[DevSNB-C+{W/A}] Before any depth stall flush (including those
 produced by non-pipelined state commands), software needs to first
 send a PIPE_CONTROL with no bits set except Post-Sync Operation != 0."

This suggests that every non-pipelined (0x79xx) command needs a
post-sync non-zero flush before it.

i965: Move post-sync non-zero flush for 3DSTATE_MULTISAMPLE.

For some reason, we put the flush in the caller, rather than just before
emitting the packet.  This is more than a cosmetic problem: BLORP calls
gen6_emit_3dstate_multisample() directly, and so it missed the flush.

i965: Also emit HIER_DEPTH and STENCIL packets when disabling depth.

From the documentation:
"[DevIVB] 3DSTATE_DEPTH_BUFFER must always be programmed along with the
 other Depth/Stencil state commands(i.e. 3DSTATE_CLEAR_PARAMS,
 3DSTATE_STENCIL_BUFFER, or 3DSTATE_HIER_DEPTH_BUFFER)."

We normally do this, but BLORP was failing to do so in the case where it
disables depth.

Not observed to fix anything yet.

The normal drawing path does this, and it's necessary on Ivybridge,
so let's try it on Sandybridge too.  It's not explicitly documented

Remove error when calling glGenQueries/glDeleteQueries while a query is active

There is nothing in the OpenGL specification which prevents the user from
calling glGenQueries to generate a new query object while another object is
active. Neither is there anything in the Mesa implementation which prevents
this. So remove the INVALID_OPERATION errors in this case.

Similarly, it is explicitly allowed by the OpenGL specification to delete an
active query, so remove the assertion for that case, replacing it with the
necesssary state updates to end the query, (clear the bindpt pointer and call
into the driver's EndQuery hook).

glsl: Move common code out of opt_algebraic's handle_expression().

Matt and I had each screwed up these common required patterns recently, in
ways that wouldn't have been noticed for a long time if not for code
review.  Just enforce it in the caller so that we don't rely on code
