Ah yes, this fixes the glibc testcase. This should make the regression tester 
a bit happier, it leaves g++.other/eh3.C as a regression and this one was 
caused by Richard Kenner's patch on Dec30.

OK to commit if it passes bootstrap? I don't expect problems though, cause 
without the reload_completed it passed even a RTL checking bootstrap.

	reload.
