Enable USB auto-reset in a hard fault.
Redirect thread-mode execution to a fail routine which throbs the LED to
indicate a hard fault. Because the fail routine runs in thread mode
with interrupts on, USB auto-reset should now work. Test by executing
some bogus instruction (e.g. *(volatile int*)0xf34fdaa = 0;) and check
that the auto-reset continues to work.
