This instruction uses two type variables: input and output. Make sure that our parser can handle it. The output type variable annotation is mandatory. Add a ValueTypeSet::example() method which is used to provide better diagnostics for a missing type variable.
Parser tests ============ This directory contains test cases for the Cretonne IL parser. Each test case consists of a `foo.cton` input file and a `foo.ref` reference output file. Each input file is run through the `cton-util cat` command, and the output is compared against the reference file. If the two are identical, the test passes.
