By "run locally" I mean that I put together a python test that run the files 
with run_test_case(), like we would do for an equivalent file in the 
functional-query workload. The idea was to verify that I had the 
RESULTS/TYPES/LABELS sections correct.

The targeted-perf workload is used by single_node_perf_run.py. I believe its 
something that Mostafa also used to run to check for regressions between 
releases. Even if no one is running it currently, it seems reasonable to me to 
add these queries for the future when there is someone paying closer attention 
to perf issues.

The targeted-stress workload seems to be pointless. Its only references in 
tests/stress/test_mini_stress.py and all of the tests there have been xfailed 
for years. Probably we should remove targeted-stress, or even better move the 
queries in workloads/tpch/ that aren't actually regular tpch queries to 
targeted-stress and modify the stress test to use them. It would also be great 
to re-enable the tests in test_mini_stress.py, even if just to ensure that the 
RESULTS/TYPES/LABELS sections stay up to date. That's all (hopefully) outside 
the scope of this patch.

Yes, the intention is for these to be run as part of downstream larger-scale 
testing. Is there any way to accomplish that currently? It seems that 
concurrent_select won't find them even if I add them to eg. 
testdata/workloads/tpch/queries/tpch-aggregations.test, as it only checks for 
test files of the form 'tpch-q*.test'
