// This is an X-macro header. It does not use `#include` guards, and instead is
// designed to be `#include`ed after the x-macro is defined in order for its
// inclusion to expand to the desired output. Macro definitions are cleaned up
// at the end of this file.
//
// Exactly one of these macros should be defined before including this header:
// - CARBON_SEMANTICS_NODE_KIND(Name)
//   Invoked for each kind of semantic node.
// - CARBON_SEMANTICS_NODE_KIND_WITH_VALUE_KIND(Name, TypeFieldKind)
//   Invoked for each kind of semantic node, along with information about
//   whether the node produces a value, and if so, what kind of value.
// - CARBON_SEMANTICS_NODE_KIND_WITH_TERMINATOR_KIND(Name, TerminatorKind)
//   Invoked for each kind of semantic node, along with information about
//   whether the node is a terminator node.
// - CARBON_SEMANTICS_NODE_KIND_WITH_IR_NAME(Name, IRName)
//   Invoked for each kind of semantic node, along with the name that is used
//   to denote this node in textual Semantics IR.
