i965: Add LINTERP/CINTERP to can_do_cmod().
LINTERP is implemented as a PLN instruction or a LINE+MAC. PLN and MAC
can do conditional mod. CINTERP is just a MOV.
total instructions in shared programs: 5952103 -> 5950284 (-0.03%)
instructions in affected programs: 324573 -> 322754 (-0.56%)

We lose the SIMD16 in one Unigine Heaven shader which appears six times
in shader-db.
