  [mlir][LLVMIR target] Fix llvm.freeze builder to prevent crashes

The freeze builder did not assign the result of creating the freeze
operation to $res, which meant that when subsequent translations (such
as a sext) tried to use that result or query its type, mlir-translate
would crash.

This fixes the issue and adds a test for it.
