clang-check crashes with option --syntax-tree-dump for "default" function

[nickhuang99]

clang-check always crash for option **--syntax-tree-dump ** when a function has key word like default or delete

`$ cat /tmp/test7.cpp 
struct Foo {
Foo() = default;
};
$ clang-check --syntax-tree-dump /tmp/test7.cpp
