Faith Ekstrand 29c4417fb8 nir: Add a backend_flags field to nir_tex_instr 
In 9ffd00bcf1 ("nir_to_tgsi: Pack our tex coords into vec4
nir_tex_src_backend[12]"), Emma added a pair of back-end sources to
nir_tex_instr to allow complex lowering to be done in NIR.  This adds a
tiny bit more hw-specific back-end information that a NIR lowering pass
can communicate to the back-end compiler.

While the opcode contains most of the information needed, some thing
such as the presence of offsets is currently only communicated via the
presence of specific source types in the source list.  This information
is gone when the texture instruction is lowered to back-end sources.
Adding a backend_flags field fixes this by allowing the lowering pass to
communicate a small amount of side-band information if needed.
