note_stores vs. PRE_DEC, POST_INC and so on

[Rask Ingemann Lambertsen]

   The comment for note_stores() (in rtlanal.c) says:

/* Call FUN on each register or MEM that is stored into or clobbered by X.
   (X would be the pattern of an insn).

   But this doesn't happen when a register is modified by e.g. a PRE_DEC
expression. Is this an oversight or intentional? If intentional, the comment
should say so and perhaps also why.
