Tests below were automatically converted from https://github.com/ariya/esprima/blob/2bb17ef9a45c88e82d72c2c61b7b7af93caef028/test/harmonytest.js.
Manually fixed locations for:
- parenthesized expressions (include brackets into expression's location)
- expression statements (excluded spaces after statement's semicolon)
- arrow and method functions (included arguments into function's location)
- template elements (excluded '`', '${' and '}' from element's location)
