Fix parsing error in exponent expressions with unary left-hand sides. #2070

Open luiscubal opened 3 years ago

Esprima (correctly) rejects expressions like -12. However, expressions like (-1)2 are valid but still rejected. This commit fixes this issue by identifying when the left operand is parenthesized.
