Fixes this snippet from SLi's afl fuzzer output:
class {
i (x = <, enum
This parsed i as a function, x as a paramter, and the stuff after < as a
template list. This then called TryConsumeDeclarationSpecifier() which
called TryAnnotateCXXScopeToken() without checking the preconditions of
this function. Check them before calling, like all other callers of
TryAnnotateCXXScopeToken() do.
A more readable reproducer that causes the same crash is
class {
void i(int x = MyTemplateClass<int, union int>::foo());
};
The reduced version used an eof token as surprising token, but kw_int works
just as well to repro and is easier to insert into a test file.
