These tests run the runtime, reflect, and sync package tests with the
two maymorestack hooks we have.
These tests only run on the longtest builders (or with
GO_TEST_SHORT=false) because we're running the runtime test two
additional times and the mayMoreStackMove hook makes it about twice as
slow (~230 seconds).
To run just these tests by hand, do
GO_TEST_SHORT=false go tool dist test -run mayMoreStack
This detected #49354, which was found as a flake on the dashboard, but
was reliably reproducible with these tests; and #49395.
