test262: class and function names should be inferred in assignment
https://bugs.webkit.org/show_bug.cgi?id=146262

Patch by Joseph Pecoraro <pecoraro@apple.com> on 2016-09-29
Reviewed by Saam Barati.

JSTests:

* stress/arrowfunction-name.js: Added.
Quick tests for arrow function names.

* stress/inferred-names.js: Added.
General test for inferred function names.

* test262.yaml:
Pass many tests checking inferred function names.

Source/JavaScriptCore:

* parser/ASTBuilder.h:
(JSC::ASTBuilder::appendParameter):
(JSC::ASTBuilder::appendArrayPatternEntry):
(JSC::ASTBuilder::appendObjectPatternEntry):
(JSC::ASTBuilder::tryInferFunctionNameInPattern):
Assign names to default value functions and classes in destructuring.

(JSC::ASTBuilder::createAssignResolve):
(JSC::ASTBuilder::createProperty):
(JSC::ASTBuilder::makeAssignNode):
Assign names to both normal and arrow functions.

* parser/Nodes.h:
(JSC::ExpressionNode::isBaseFuncExprNode):
Both functions and arrow functions infer name, they both extend
this base so give the base an is check.
