Increment of extended vector type

>From the OpenCL 1.1 Specification, 6.3.c, "The arithmetic post- and
pre-increment and decrement operators (-- and ++) operate on built-in scalar
and vector types except the built-in scalar and vector float types.  All unary
operators work component-wise on their operands."  

The attached OpenCL kernel program relying on this behavior fails semantic
checking with the error:
test.cl:5:7: error: cannot increment value of type 'int4'
