[committed] Fix expected test output on hppa

[Jeff Law via Gcc-patches]

Recent changes in the hoisting code change the optimized gimple for the 
shadd-3 testcase on the PA.  That in turn changes the number of expected 
shadd instructions.

I'm not entirely sure the test is actually testing what we want anymore 
since I don't see a CSE for postreload to discover.  But I did verify 
that the number of shadd instructions is sane, so I just changed the 
count in the obvious way.

Pushed to the trunk.
