Iago Toral Quiroga 6c418dfa42 intel/compiler: fix node interference of simd16 instructions 
SIMD16 instructions need to have additional interferences to prevent
source / destination hazards when the source and destination registers
are off by one register.

While we already have code to handle this, it was only running for SIMD16
dispatches, however, we can have SIDM16 instructions in a SIMD8 dispatch.
An example of this are pull constant loads since commit b56fa830c6,
but there are more cases.

This fixes a number of CTS test failures found in work-in-progress
tests that were hitting this situation for 16-wide pull constants
in a SIMD8 program.

appropriate, you should ask your question on `Freenode's #dri-devel
<irc://chat.freenode.net#dri-devel>`_, someone will redirect you if
necessary.
Remember that not everyone is in the same timezone as you, so it might
take a while before someone qualified sees your question.
