V2: - emit `sample` parameter properly for multisample texelFetch()
- fix spurious whitespace change
- introduce a new opcode ir_txf_ms rather than overloading the
existing ir_txf further. This makes doing the right thing in
the driver somewhat simpler.
V3: - fix weird whitespace
V4: - don't forget to include the new opcode in tex_opcode_strs[]
(thanks Kenneth for spotting this)

For the UBO lowering pass, I want to see the whole dereference chain for
replacing, not the innermost ir_dereference_variable.

One unique aspect of TXS is that it doesn't have a coordinate.

Having these as actual integer values makes it difficult to implement
the texture*Offset built-in functions, since the offset is actually a
function parameter (which doesn't have a constant value).
The original rationale was that some hardware needs these offset baked
into the instruction opcode. However, at least i965 should be able to
support non-constant offsets. Others should be able to rely on inlining
and constant propagation.
