For reduction purposes, it might be useful to factor out the auto type
deduction on the return. I think you can do that with the help of `-Xclang
-ast-dump`. E.g., for this function:
auto f() { return 1; };
the AST dump tells me the return type is `int`:
|-FunctionDecl 0x1508e5698 <t.cpp:1:1, col:22> col:6 f 'int ()'
| `-CompoundStmt 0x1508e5928 <col:10, col:22>
| `-ReturnStmt 0x1508e5918 <col:12, col:19>
| `-IntegerLiteral 0x1508e5780 <col:19> 'int' 1
You could then replace the `auto` with the type given in the dump.
