asan_ignore: Explicitly list ignored behavior fcns

Browse Source 
Overflow on signed integers is undefined behavior.  Perl does whatever
the underlying compiler does in this case.  Previously this file used a
wildcard which could specify more functions than we really expect to see
this potential overflow from.  It is safer to mention explicitly all the
functions.
