Quick assist "Join if statement with inner if" drops comments

[srikanth-sankaran]

This block of code:

        if ((this.bits & ASTNode.SwitchRuleBlock) != 0) { // switch rule blocks shouldn't fall through ...
		if (flowInfo != FlowInfo.DEAD_END) {
			if (flowContext.associatedNode instanceof SwitchExpression) { // ... demand that for expression switch
				currentScope.problemReporter().switchExpressionBlockCompletesNormally(this);
			} else { // ... enforce that for statement switch, by an automagic break
				flowContext.recordBreakFrom(flowInfo);
				return FlowInfo.DEAD_END;
			}
		}
	}

becomes this:

        if ((this.bits & ASTNode.SwitchRuleBlock) != 0 && flowInfo != FlowInfo.DEAD_END) {
		if (flowContext.associatedNode instanceof SwitchExpression) { // ... demand that for expression switch
			currentScope.problemReporter().switchExpressionBlockCompletesNormally(this);
		} else { // ... enforce that for statement switch, by an automagic break
			flowContext.recordBreakFrom(flowInfo);
			return FlowInfo.DEAD_END;
		}
	}

See that the original comment // switch rule blocks shouldn't fall through ... has vanished
