Subject: 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
__addressable_tracing_set_default_clock8649 - 8 +8
__addressable_tracer_init_tracefs8631 - 8 +8
__addressable_ftrace_dump8383 - 8 +8
__addressable_clear_boot_tracer8632 - 8 +8
__addressable_tracing_set_default_clock8650 8 - -8
__addressable_tracer_init_tracefs8632 8 - -8
__addressable_ftrace_dump8384 8 - -8
__addressable_clear_boot_tracer8633 8 - -8
trace_default_header 663 642 -21
tracing_mark_raw_write 406 355 -51
tracing_mark_write 624 557 -67
Total: Before=63889, After=63750, chg -0.22%
They're small and in .discard, so ignore them, leading to more useful
