i965/vec4: Take into account all instruction fields in CSE instructions_match().

Browse source 
Most of these fields affect the behaviour of the instruction, but
apparently we currently don't CSE the kind of instructions for which
these fields could make a difference in the VEC4 back-end.  That's
likely to change soon though when we start using send-from-GRF for
texture sampling and surface access messages.
