i965/fs: Rudimentary support for non-floating point texture results.
Not all texturing operations return floating point data. For example,
the resinfo message (textureSize or TXS) returns integer data. In the
future, we'll also add integer texture support.
ir_texture's type field contains this information; use its base type to
appropriately type the destination register. We want to keep it as a
four component vector, however, since SIMD8 samplers always have a
response length of 4.
