Description

The tracer currently does not decode the pseudo instruction.
Use it once it is supported by more tools. Actually not quite which, but it was recently mentioned in https://github.com/llvm/llvm-project/commit/249d7de1190f50178181d2477aa661cd252e294c

Research direction

Start by examining the tracer's instruction-decoding path and the referenced LLVM commit for the pseudo zext.[b|h] form. Confirm which tools support the instruction before changing behavior; done means the tracer decodes it when that support is available.
