perf stat: Introduce --repeat forever
...
The following patch causes 'perf stat --repeat 0' to be interpreted as
'forever', displaying the stats for every run.
We act as if a single run was asked, and reset the stats in each
iteration. In this mode SIGINT is passed to perf to be able to stop the
loop with Ctrl+C.

perf tests: Test breakpoint overflow signal handler
...
Adding automated test for breakpoint event signal handler checking if
it's executed properly.
The test is related to the proper handling of the RF EFLAGS bit on
x86_64, but it's generic for all archs.
First we check the signal handler is properly called and that the
following debug exception return to user space wouldn't trigger
recursive breakpoint.
This is related to x86_64 RF EFLAGS bit being managed in a wrong way.
Second we check that we can set breakpoint in signal handler, which is
not possible on x86_64 if the signal handler is executed with RF EFLAG
set.
This test is inpired by overflow tests done by Vince Weaver.
