clover: Optionally return context's devices from clGetProgramInfo()

The spec allows clGetProgramInfo() to return information about either
the devices associated with the program or the devices associated
with the context.  If there are no devices associated with the program,

glsl: Rework interface block linking.

Previously, when doing intrastage and interstage interface block
linking, we only checked the interface type; this prevented us from
catching some link errors.

We now check the following additional constraints:

- For intrastage linking, the presence/absence of interface names must
  match.

- For shader ins/outs, the interface names themselves must match when
  doing intrastage linking (note: it's not clear from the spec whether
  this is necessary, but Mesa's implementation currently relies on
  it).

- Array vs. nonarray must be consistent, taking into account the
  special rules for vertex-geometry linkage.

- Array sizes must be consistent (exception: during intrastage
  linking, an unsized array matches a sized array).

Note: validate_interstage_interface_blocks currently handles both
uniforms and in/out variables.  As a result, if all three shader types
are present (VS, GS, and FS), and a uniform interface block is
mentioned in the VS and FS but not the GS, it won't be validated.  I
plan to address this in later patches.

Fixes the following piglit tests in spec/glsl-1.50/linker:
- interface-blocks-vs-fs-array-size-mismatch
- interface-vs-array-to-fs-unnamed
- interface-vs-unnamed-to-fs-array
- intrastage-interface-unnamed-array

v2: Simplify logic in intrastage_match() for handling array sizes.
Make extra_array_level const.  Use an unnamed temporary
interface_block_definition in validate_interstage_interface_blocks()'s
first call to definitions->store().

i965: Fix vertical alignment for multisampled buffers.

From the Sandy Bridge PRM, Vol 1 Part 1 7.18.3.4 (Alignment Unit
Size):

    j [vertical alignment] = 4 for any render target surface is
    multisampled (4x)

From the Ivy Bridge PRM, Vol 4 Part 1 2.12.2.1 (SURFACE_STATE for most
messages), under the "Surface Vertical Alignment" heading:

    This field is intended to be set to VALIGN_4 if the surface was
    rendered as a depth buffer, for a multisampled (4x) render target,
    or for a multisampled (8x) render target, since these surfaces
    support only alignment of 4.

Back in 2012 when we added multisampling support to the i965 driver,
we forgot to update the logic for computing the vertical alignment, so
we were often using a vertical alignment of 2 for multisampled
buffers, leading to subtle rendering errors.

Note that the specs also require a vertical alignment of 4 for all
Y-tiled render target surfaces; I plan to address that in a separate
patch.
