Introduce clang-query tool. This tool is for interactive exploration of the Clang AST using AST matchers. It currently allows the user to enter a matcher at an interactive prompt and view the resulting bindings as diagnostics, AST pretty prints or AST dumps. Example session: $ cat foo.c void foo(void) {} $ clang-query foo.c -- clang-query> match functionDecl() Match #1: foo.c:1:1: note: "root" binds here void foo(void) {} ^~~~~~~~~~~~~~~~~ 1 match.
