No test actually does this, but this makes the option behave like the corresponding one in run.py. This was broken by commit b8b23aa80eefe84187d6ba364d06496c90c53bdb (https://reviews.llvm.org/D99242) which introduced quoting; instead of quoting the whole space separated list, quote each individual argument.
