* storage is part of the call frame.
* VAR_DEAD_HASH 1 means that this var's entry in the hashtable

* element, so it is not legal for it to be an
* array itself (the VAR_ARRAY flag had better
* not be set).
* VAR_NAMESPACE_VAR - 1 means that this variable was declared as a
* namespace variable. This flag ensures it
* persists until its namespace is destroyed or
* until the variable is unset; it will persist
* even if it has not been initialized and is
* marked undefined. The variable's refCount is

* VAR_TRACED_WRITE
* VAR_TRACED_UNSET
* VAR_TRACED_ARRAY
* VAR_TRACE_ACTIVE - 1 means that trace processing is currently

* read or write accesses should not cause trace
* procedures to be called and the variable can't
* be deleted.
* VAR_SEARCH_ACTIVE
*
* The following additional flags are used with the CompiledLocal type defined
* below:
*
* VAR_ARGUMENT - 1 means that this variable holds a procedure
* argument.
* VAR_TEMPORARY - 1 if the local variable is an anonymous
* temporary variable. Temporaries have a NULL
* name.
* VAR_RESOLVED - 1 if name resolution has been done for this
* variable.
* VAR_IS_ARGS 1 if this variable is the last argument and is
