[pushed] rtl-ssa: Fix reversed comparisons in accesses.h comment

[pushed] rtl-ssa: Fix reversed comparisons in accesses.h comment

[Richard Sandiford]

Noticed while looking at something else that the comment above
def_lookup got the description of the comparisons the wrong way
round.

Tested on aarch64-linux-gnu and pushed as obvious.
