Right, for ARM, in order to match return instructions, 'lr' must be
found to be the operand of the branch instruction, which is not
contained in the 'name' variable passed to ins__find().

I don't want this to inhibit acceptance of this series, however: I plan
on addressing it afterwards, unless, of course, it is perceived as a
problem somehow (compatibility-wise, it is not because it is an error
at the moment).
