[clang] Fix JSON AST output when a filter is used

[woodruffw]

Summary

Without this, the combination of -ast-dump=json and -ast-dump-filter FILTER produces invalid JSON: the first line is a string that says Dumping $SOME_DECL_NAME: .

[woodruffw]

Updated the AST dump tests for JSON to refute the presence of the Dumping prefix.

Also, updated the gen_ast_dump_json_test.py generator to work with Python 3 and to behave better without the presence of the Dumping: sentinels.

[woodruffw]

Gentle ping for review on this!

[woodruffw]

Another gentle ping for review.

[woodruffw]

Increase the context for the patch.

Another gentle ping for review.

[aaron.ballman]

The changes LGTM, though I'm not an expert in python.

[xgupta]

@woodruffw Please rebase the patch. clang/test/AST/ast-dump-if-json.cpp testcase is not applying cleanly. If you don't commit access, I can commit on your behalf. Thanks.

[woodruffw]

Resolve conflicts.
