Mainline testing on hppa2.0w-hp-hpux11.23 shows a new FAIL

FAIL: gcc.dg/tree-ssa/20030807-2.c scan-tree-dump-times if  0

but this may not be indicative of a problem with the patch as there's 
something odd going on with various such tests at present (bug 22176).  
The patch does change assembly output for the test given in bug 22051 in 
what I think is the right way.  I'll see what 4.0 branch testing shows.
