This fixes an ARM assembler crash - regression test added.

Turns out that this was the root cause of PR19621. We found a crasher
only recently (likely due to improvements elsewhere in the SLP
vectorizer) but the reduced test case failed all the way back to here.
I've confirmed that reverting this patch both fixes the reduced test
case in PR19621 and the actual source file that led to it, so it seems
to really be rooted here. I've replied to the commit thread with
discussion of my (feeble) attempts to debug this. Didn't make it very
far, so reverting now that we have a good test case so that things can
get back to healthy while the debugging carries on.

removal. We can't just blindly increment (or decrement) the adapted
iterator when the value is null because doing so can walk past the end
(or beginning) and keep inspecting the value. The fix I've implemented
is to restrict this further to a forward iterator and add an end
iterator to the members (replacing a member that had become dead when
I switched to the adaptor base!) and using that to stop the iteration.

I'm not entirely pleased with this solution. I feel like forward
iteration is too restrictive. I wasn't even happy about bidirectional
iteration. It also makes the iterator objects larger and the iteration
loops more complex. However, I also don't really like the other
alternative that seems obvious: a sentinel node. I'm still hoping to
come up with a more elegant solution here, but this at least fixes the
MSan and Valgrind errors on this code.

Summary:
There are two functional changes:
1) The directive is not expanded for the ASM->ASM code path.
2) If PIC is not set, there's no expansion for the ASM->OBJ code path (same behaviour as GAS).

This fixes the memory leak introduced with the initial addition of support for
WoA stack probing.  Now that the pseudo-instruction expansion can handle an
external symbol, use that to generate the load which simplifies the logic as
well as avoids the memory leak.

This enhances the expansion of the mov32imm pseudo-instruction to support an
external symbol reference.  This is motivated by a simplification of the stack
probe emission for Windows on ARM (and fixing a leak).

Previously the input file for the lib.exe command would be removed

GCC emits DW_AT_object_pointer /everywhere/ (declaration, abstract
definition, inlined subroutine), but it looks like GCC relies on it
being somewhere other than the declaration, at least. I'll experiment
further & can hopefully still remove it from the inlined_subroutine.

This reverts commit r207705.

They just don't need to be there - they're inherited from the abstract
definition. In theory I would like them to be inherited from the
declaration, but the DWARF standard doesn't quite say that... we can
probably do it anyway but I'm less confident about that so I'll leave it
for a separate commit.

Not all address taken blocks get inlined. The reason is
that a blocks new address is known only when it is cloned. But e.g.
a branch instruction in a different block could need that address earlier
while it gets cloned. The solution is to collect the set of all
blocks that can potentially get inlined and compute a new block address
up front. Then clone and cleanup.
