shouldInstrument returns false for ignored paths specified in coveragePathIgnorePatterns (e.g. node_modules)
shouldInstrument returns false for test files matching testMatch or testRegex
shouldInstrument returns true for test files when overridden by forceCoverageMatch
shouldInstrument returns false for JSON files and files in __mocks__ directories

handlePotentialSyntaxError returns non-SyntaxError instances unmodified without throwing
handlePotentialSyntaxError throws enhanced SyntaxError containing code frame and Jest diagnostic explanation
