paulberry@google.com 0e488419b6 Implement the new '??=' operator in analyzer.
As in r44802, the new operator is only accepted by the tokenizer if
the command-line option "--enable-null-aware-operators" is supplied.
Only static analysis of '??=' is implemented; however, the tests in
tests/language will verify behavior once it is implemented.
