I believe this should now be fixed. Do we want a testcase, and if so is there a
good way to scan for the stack usage pattern (as observed in the assembler)?
One can scan-assembler times for addq.*%rsp, but fixing the constant 72 seems
rather fragile, and I don't see a dejagnu way to scan for the constant being
the same in each demoN()...
And the case of unions is still not handled!!
