Metadata node.

Metadata nodes can be uniqued, like constants, or distinct. Temporary metadata nodes (with full support for RAUW) can be used to delay uniquing until forward references are known. The basic metadata node is an MDTuple.

There is limited support for RAUW at construction time. At construction time, if any operand is a temporary node (or an unresolved uniqued node, which indicates a transitive temporary operand), the node itself will be unresolved. As soon as all operands become resolved, it will drop RAUW support permanently.

If an unresolved node is part of a cycle, resolveCycles() needs to be called on some member of the cycle once all temporary nodes have been replaced.

MDNodes can be large or small, as well as resizable or non-resizable. Large MDNodes' operands are allocated in a separate storage vector, whereas small MDNodes' operands are co-allocated. Distinct and temporary MDnodes are resizable, but only MDTuples support this capability.

Clients can add operands to resizable MDNodes using push_back().

If M is provided, metadata nodes will be numbered canonically; otherwise, pointer addresses are substituted.

Note: this uses an explicit overload instead of default arguments so that the nullptr version is easy to call from a debugger.

Check if node is fully resolved.

If isTemporary(), this always returns false; if isDistinct(), this always returns true.

If isUniqued(), returns true if this has already dropped RAUW support (because all operands are resolved).

As forward declarations are resolved, their containers should get resolved automatically. However, if this (or one of its operands) is involved in a cycle, resolveCycles() needs to be called explicitly.
