[PATCH] bloat-o-meter: ignore __addressable_ symbols

[Rasmus Villemoes]

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

add/remove: 0/0 grow/shrink: 0/3 up/down: 0/-139 (-139)
Function                                     old     new   delta
trace_default_header                         663     642     -21
tracing_mark_raw_write                       406     355     -51
tracing_mark_write                           624     557     -67
Total: Before=63721, After=63582, chg -0.22%
