bst_vs_heap_vs_hashmap: create nicer version with separated benchmarks
...
One data structure per executable, and gem5 instrumented versions in
separate executables.
Create the allowed_emulators path_properties property.
TODO: wire it up to benchmark result generation and remove the old version.

Selection with --mode userland (default because has x86_64) or --mode baremetal.

the = was added on macros so var was not possible.
Define the main function directly in assembly, the C driver was useless.

--quit-after-boot: fix for gem5, update path to gem5.sh
Improve the printing of results and errors:
- remove newlines from IDs at the end for ./test-boot
- remove newlines from progress for __call__ commands and don't print executed commands at all,
otherwise there are too many lines per test and it is hard to tell what is going on
- print backtraces for any exception in the threads (bugs while developing this code)
Tests across different archs and emulators are still not running in parallel,
which is a huge loss. TODO.
thread_pool: introduce with API. This was motivate by test-boot, I've had enough
of doing separate error handling for each loop type! Greatly dries up the code, awesome.
common: make --all-emulators work properly with native hopefully for the last time,
./test-baremetal was still failing.
gem5: don't pass --command-line for baremetal. Maybe later we can use it to actually
pass command line arguments to main()? To be seen.
