Fix several crashes of C++ demangler on fuzzed input.
libiberty/
* cp-demangle.c (d_dump): Fix syntax error.
(d_identifier): Adjust type of len to match d_source_name.
(d_expression_1): Fix out-of-bounds access. Check code variable for
NULL before dereferencing it.
(d_find_pack): Do not recurse for FIXED_TYPE, DEFAULT_ARG and NUMBER.
(d_print_comp_inner): Add NULL pointer check.
* cp-demangle.h (d_peek_next_char): Define as inline function when
CHECK_DEMANGLER is defined.
(d_advance): Likewise.
* testsuite/demangle-expected: Add new testcases.
