Why PLUS_EXPR and MULT_EXPR? Pointer arithmetic should use
POINTER_PLUS_EXPR exclusively. I don't think you should be seeing
PLUS_EXPRs here. The MULT_EXPR show up in scaling expressions?
MULT_EXPR shows up in array indexing, since the index is multiplied by
the size of the element; gcc converts everything to bytes before
lowering. I added PLUS_EXPR for completeness, since I'm sure someone
will write an expression like array[i+1] at some point. :-)
But you should not see such an expression in gimple. The array index is
always a gimple_val.
