evaluate2.sh: Check output of warmup run and abort early if failed (#333)

* refactor: replace xtrace with "print_and_execute" function

* nit: stylize error messages

* replace out_expected.txt with measurements_1B.out

* print

* prevent errors on cleanup

* run tests and check warmup run output before running benchmark

* move "git diff" pretty diff output to test.sh

* Ensure "set -e" is re-enabled if we followed a "continue" branch

* add timeouts to test.sh invocations

* use diff with tocsv.sh to show differences on failed test

* add --quiet mode to test.sh

* move prepare_$fork.sh invocation to right below hyperfine since test.sh also invokes it

* Revert "add --quiet mode to test.sh"

This reverts commit 13e9fb7f395c1bd64a62528b8349803bc1366941.

* use tee to capture test output to a temp file and print contents on failure
