i965/vec4: adding vec4_cmod_propagation optimization
vec4 port of fs_cmod_propagation.
Shader-db results (no vec4 grepping):
total instructions in shared programs: 6240413 -> 6235841 (-0.07%)
instructions in affected programs: 401933 -> 397361 (-1.14%)
total loops in shared programs: 1979 -> 1979 (0.00%)

HURT: 0
v2: remove extra space and combine two if blocks, as suggested by
Matt Turner
v3: add condition check to bail out if current inst and inst being
scanned has different writemask, as pointed by Matt Turner
v3: updated shader-db numbers
v4: remove block from foreach_inst_in_block_*_starting_from after
