FunctionContext::Allocate() and FunctionContext::AllocateLocal() used to return NULL for zero length allocations. This makes it hard to distinguish between allocation failures and zero length allocations. Such confusion may lead to DCHECK failure in the macro RETURN_IF_NULL() in debug builds or access to NULL pointers in non-debug builds. This change fixes the problem above by returning NULL only if there is allocation failure. Zero-length allocations will always return a dummy non-NULL pointer.
