glsl: fix interpolateAtXxx(some_vec[idx], ...) with dynamic idx

The dynamic index of a vector (not array!) is lowered to a sequence of
conditional assignments. However, the interpolate_at_* expressions
require that the interpolant is an l-value of a shader input.

So instead of doing conditional assignments of parts of the shader input
and then interpolating that (which is nonsensical), we interpolate the
entire shader input and then do conditional assignments of the interpolated
result.

glsl: allow any l-value of an input variable as interpolant in interpolateAt*

The intended rule has been clarified in GLSL 4.60, Section 8.13.2
(Interpolation Functions):

   "For all of the interpolation functions, interpolant must be an l-value
    from an in declaration; this can include a variable, a block or
    structure member, an array element, or some combination of these.
    Component selection operators (e.g., .xy) may be used when specifying
    interpolant."

For members of interface blocks, var->data.must_be_shader_input must be
determined on-the-fly after lowering interface blocks, since we don't want
to disable varying packing for an entire block just because one input in it
is used in interpolateAt*.

gallium: increase pipe_sampler_view::target bitfield size for MSVC

MSVC treats enums as being signed.  The 4-bit target field isn't large
enough to correctly store the value 8 (for PIPE_TEXTURE_CUBE_ARRAY).
The bitfield value 0x8 was being interpreted as -8 so matching the
target with PIPE_TEXTURE_CUBE_ARRAY in switch statements, etc. was
failing.

To keep the structure size the same, we reduce the format field from
16 bits to 15.  There don't appear to be any other enum bitfields
which need to be adjusted.

This fixes a number of Piglit cube map array tests.
