Standardize BinaryOp and UnaryOp nodes
9e33cea 
These were previously called "BinaryExpr" and "Unary"; besides being
inconsistent, it's also not correct to say "binary expression" or "unary
expression", as it's the operators that have arities, not the
expression. Adjust the naming of the variants accordingly.
@benesch
Split operators by arity
ae25dce 
It is useful downstream to have two separate enums, one for unary
operators and one for binary operators, so that the compiler can check
exhaustiveness. Otherwise downstream consumers need to manually encode
which operators are unary and which operators are binary when matching
on an Operator enum.
@benesch benesch force-pushed the expr-consistency branch from b670e12 to ae25dce Compare June 11, 2019 03:03
