Include the name of the variable when diagnosing uses and defs of undeclared variables. And, add an assert to def_var to check that the declared type of a variable matches the value type of the def. With this change, `Variable` implementations must now implement `Debug`.
This crate provides a straightforward way to create a
Cretonne IR function and fill it with
instructions translated from another language. It contains an SSA construction
module that provides convenient methods for translating non-SSA variables into
SSA Cretonne IR values via use_var and def_var calls.
