A patch that fixes the immediate problem

This is a bug in the ia64 backend, which puts autoinc addressing modes into
COND_EXECs, failing to notice that they have side effects.

This part of the problem can be fixed with the patch I'm attaching, but it
doesn't work: the rest of the ia64 backend expects that this kind of insn can
always be split.

At this point I'm leaving it for an ia64 maintainer to fix.
