Issue #1658 - Part 4: Fix optional chaining assertions and remove unreachable code
This includes the following:
Bug 1611777 - Part 1: Report syntax error for optional property access in self-hosting code. r=yulia!
Bug 1611777 - Part 2: Merge same blocks in emitDeleteOptionalChain(). r=yulia!
Bug 1611777 - Part 3: N/A
Bug 1611777 - Part 4: `super` can't occur on the left-hand side of an optional chain
Bug 1611777 - Part 5: Remove unnecessary super-handling in optional delete. r=yulia!
The child node of a DeleteOptionalChainExpr node can't be a super-property
accessor, so we can remove this code.
Bug 1611777 - Part 6: Crash for unexpected super-base in optional call. r=yulia!
Bug 1611777 - Part 7: Add missing entries to list of valid optional chain start expressions. r=yulia!
Bug 1611777 - Part 8: Add missing emitGet in emitOptionalElemExpression. r=yulia!
Aligns emitOptionalElemExpression() with emitOptionalDotExpression(), so it's
easier to compare both methods against each other.
Bug 1611777 - Part 9: Replace an if-statement with an assertion. r=yulia!
Bug 1611777 - Part 10: N/A
Bug 1611777 - Part 11: Support optional chaining in class heritage expression. r=yulia!
Bug 1611777 - Part 12: Use optionalExpr() for update expressions to match spec grammar. r=yulia!
Using optionalExpr matches the spec grammar more closely. This change also
modifies the reported error message. ++a?.b reported before this change
"unexpected token: '?.'", but now reports "invalid increment/decrement operand".
Bug 1611777 - Part 13: N/A
Bug 1611777 - Part 14: Simplify two lines in optionalExpr(). r=yulia!
We don't need to test for tt == TokenKind::Eof when we return for tt != TokenKind::OptionalChain anyway. Omit local variable for the result value and instead use a tail-call. This matches the local style in the parser more closely.
Bug 1611777 - Part 15: Support FunCall/FunApply optimisations for optional chaining. r=yulia!
Bug 1611777 - Part 16: Pass through ValueUsage in optional chains. r=yulia
