  -----------
  [GCDAProfiling] Suppress -Wprio-ctor-dtor for GCC>=9 and remove unused write_string/length_of_string

The `__attribute__((destructor(100)))` diagnostic does not have a
warning option in GCC 8 (before r264853) and thus cannot be suppressed.

(cherry picked from commit 1cfde143e82aeb47cffba436ba7b5302d8e14193)
