When the parser is live, print out the location and spelling of its current token.
For example:
Stack dump:
0. Program arguments: clang t.cpp
1. t.cpp:4:8: current parser token: ';'
2. t.cpp:3:1: parsing struct/union/class body 'x'
Abort
It is weird that the parser is always "underneath" any parse context
actions, but the parser is created first.
