Detailed Description
Represents a prvalue temporary that written into memory so that a reference can bind to it.
Prvalue expressions are materialized when they need to have an address in memory for a reference to bind to. This happens when binding a reference to the result of a conversion, e.g.,
const int &r = 1.0;
Here, 1.0 is implicitly converted to an int. That resulting int is then materialized via a MaterializeTemporaryExpr, and the reference binds to the temporary. MaterializeTemporaryExprs are always glvalues (either an lvalue or an xvalue, depending on the kind of reference binding to it), maintaining the invariant that references always bind to glvalues.

SourceLocation tokens are not useful in isolation - they are low level value objects created/interpreted by SourceManager. We assume AST clients will have a pointer to the respective SourceManager.
