Stress test for MPSC

[stepancheg]

concurrent_recv_timeout_and_upgrade reproduces a problem 100%
times on my MacBook with command:

./x.py test --stage 0 ./src/test/run-pass/mpsc_stress.rs

Thus it is commented out.

Other tests cases were useful for catching another test cases
which may arise during the fix.

This diff is a part of my previous rewrite attempt: #42883
