[PATCH 07/19] commands: ubsan: hide pointer provenance used to trigger UB

[Ahmad Fatoum]

The ubsan command invokes various sort of undefined behavior to verify
that the Undefined Behavior Sanitizer works as expected. Compiler warns
about some of this, which is not helpful, so work around the warning.
