[kvm-unit-tests PATCH v2 1/4] lib/report: Add helper methods to clear multiple prefixes

[Andrew Jones <andrew.jones@linux.dev>]

Also, let's separate this patch into its own series where we also apply
it with a second patch to the current riscv/sbi.c in order to remove a
bunch of pops.

Thanks,
drew
