Fix a bug in FileCheck that wouldn't let define variables as follows: ; CHECK: [[VAR:[a-z]]] The problem was that to find the end of the regex var definition, it was simplistically looking for the next ]] and finding the incorrect one. A better approach is to count nesting of brackets (taking escaping into account). This way the brackets that are part of the regex can be discovered and skipped properly, and the ]] ending is detected in the right place. llvm-svn: 169109
