; When inlining through a byval call site, the inliner creates allocas which may
; be used by inlined calls, so any inlined calls need to have their 'tail' flags
; cleared. If not then you can get nastiness like with this testcase, where the
; (inlined) call to 'ext' in 'foo' was being passed an uninitialized value.
