Log Message:

ASSERTION FAILED: !reg.isConstant() caused by destructuring assignment

Reviewed by Yusuke Suzuki and Mark Lam.
RETURN macro of CommonSlowPaths.cpp accesses destination register via GET macro,
which asserts it to be non-constant. This change fixes the failing isConstant()
assertion for OpToPropertyKeyOrNumber emitted in ObjectPatternNode::bindValue()
by using temporary register if rest element is absent, while carefully
preserving
existing logic in case of m_containsRestElement.
* JSTests/stress/regress-279863.js: Added.
* Source/JavaScriptCore/bytecompiler/NodesCodegen.cpp:
