Error message improvement for unexpected tokens in the following situations: * A word was parsed that seems to have a low edit distance from a known common keyword * A word was parsed that seems to be a known common keyword and a name _without_ a space in-between * Parsing in a particular type of node (mostly a class property declaration) got a different word or token than expected ___ * Specific diagnostic suggestions for unexpected keywords or identifier * Don't reach into there, that's not allowed * Improved error when there is already an initializer * Specific module error message for invalid template literal strings * Skip 'unexpected keyword or identifier' diagnostics for declare nodes * Improve error for function calls in type positions * Switch class properties to old diagnostic * Corrected errors in class members and reused existing textToKeywordObj map * Corrected more baselines from the merge * Update src/compiler/parser.ts Co-authored-by: Daniel Rosenwasser <DanielRosenwasser@users.noreply.github.com> * Mostly addressed feedback * Clarified function call type message * Split up and clarified parsing vs error functions * Swap interface name complaints back, and skip new errors on unknown (invalid) tokens * Used tokenToString, not a raw semicolon * Inline getExpressionText helper * Remove remarks in src/compiler/parser.ts Co-authored-by: Daniel Rosenwasser <DanielRosenwasser@users.noreply.github.com>
