Duncan Sands 1978426a94 Revert r70876 and add a testcase (@c7) showing the problem: ...

bits captured, but the pointer marked nocapture.  In fact
I now recall that this problem is why only readnone functions
returning void were considered before!  However keep a small
fix that was also in r70876: a readnone function returning
void can result in bits being captured if it unwinds, so
test for this.
