Still can't bootstrap hppa2.0-hp-hpux10.20.
We get further than before (the duplicate-include problem is gone),
but still bomb early in stage 2. The latest failure is

The relevant comment says
/* If we're trying to delete a prologue or epilogue instruction
that isn't flagged as possibly being dead, something is wrong.
But if we are keeping the stack pointer depressed, we might well
be deleting insns that are used to compute the amount to update
it by, so they are fine. */
Clues, Jeff?
