Perform replacement of access relations and creation of new arrays according to the packing transformation
This is the third patch to apply the BLIS matmul optimization pattern on matmul
kernels (http://www.cs.utexas.edu/users/flame/pubs/TOMS-BLIS-Analytical.pdf).
BLIS implements gemm as three nested loops around a macro-kernel, plus two
packing routines. The macro-kernel is implemented in terms of two additional
loops around a micro-kernel. The micro-kernel is a loop around a rank-1
(i.e., outer product) update. In this change we perform replacement of
the access relations and create empty arrays, which are steps to implement
the packing transformation. In subsequent changes we will implement copying

Fix a race in Broadcaster/Listener interaction
Summary:
The following problem was occuring:
- broadcaster B had two listeners: L1 and L2 (thread T1)
- (T1) B has started to broadcast an event, it has locked a shared_ptr to L1 (in
ListenerIterator())
- on another thread T2 the penultimate reference to L1 was destroyed (the transient object in B is
now the last reference)
- (T2) the last reference to L2 was destroyed as well
- (T1) B has finished broadcasting the event to L1 and destroyed the last shared_ptr
- (T1) this triggered the destructor, which called into B->RemoveListener()
- (T1) all pointers in the m_listeners list were now stale, so RemoveListener emptied the list
- (T1) Eventually control returned to the ListenerIterator() for doing broadcasting, which was
still in the middle of iterating through the list
- (T1) Only now, it was holding onto a dangling iterator. BOOM.
I fix this issue by making sure nothing can interfere with the
iterate-and-remove-expired-pointers loop, by moving this logic into a single function, which
first locks (or clears) the whole list and then returns the list of valid and locked Listeners
for further processing. Instead of std::list I use an llvm::SmallVector which should hopefully
offset the fact that we create a copy of the list for the common case where we have only a few
listeners (no heap allocations).
A slight difference in behaviour is that now RemoveListener does not remove an element from the
list -- it only sets it's mask to 0, which means it will be removed during the next iteration of
GetListeners(). This is purely an implementation detail and it should not be externally
noticable.
I was not able to reproduce this bug reliably without inserting sleep statements into the code,
so I do not add a test for it. Instead, I add some unit tests for the functions that I do modify.

It's imperative that the pointer increments be located in the latch block and not the header block; if not, we cannot use post-increment loads and stores and we have to keep both the post-inc and pre-inc values around until the end of the latch which bloats register usage.

Add private option to change build dialect from C++11
Although libc++ only requires C++11 to build, there are other

IDE's may not highlight any C++14/C++17 in the headers when
configured for C++11. This patch add's a private option for

[IRCE] Don't iterate on loops that were cloned out
IRCE has the ability to further version pre-loops and post-loops that it
created, but this isn't useful at all. This change teaches IRCE to
leave behind some metadata in the loops it creates (by cloning the main
loop) so that these new loops are not re-processed by IRCE.
Today this bug is hidden by another bug -- IRCE does not update LoopInfo
properly so the loop pass manager does not re-invoke IRCE on the loops
it split out. However, once the latter is fixed the bug addressed in
this change causes IRCE to infinite-loop in some cases (e.g. it splits
out a pre-loop, a pre-pre-loop from that, a pre-pre-pre-loop from that
and so on).
