bloat-o-meter: ignore __addressable_ symbols

Since __LINE__ is part of the symbol created by __ADDRESSABLE, almost
any change causes those symbols to disappear and get reincarnated, e.g.

add/remove: 4/4 grow/shrink: 0/3 up/down: 32/-171 (-139)
Function                                     old     new   delta

They're small and in .discard, so ignore them, leading to more useful

add/remove: 0/0 grow/shrink: 0/3 up/down: 0/-139 (-139)
