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.
