asan_ignore: exclude Perl_pp_left_shift()
<< in perl maps directly to << in C, so don't warn about it when the RHS
is too big.
Fixes e.g.:
print 1 << 64
use integer; print 1 << 63
Typical ASan warning:
pp.c:1893:2: runtime error: left shift of 1 by 63 places cannot be represented in type 'IV' (aka 'long')
