A new variable with no uses?
This one is quite ugly: the pre-existing code has two locals named
"note", both of type rtx, with one shadowing the other. This patch
introduces a third, within the scope where the name "note" is used for
insns. In the other scopes the two other "note" variables are used for
find_reg_note. In each case, the name "note" is written to before use.
So in my defense, the existing code already had shadowing of locals...
but I guess that's not much of a defense, and it would be better to
introduce a different name, and rename the uses in the appropriate
scope.
