two improvements to RemoveAccessedObjects:
1. if the underlying pointer passed in can be resolved
   to any argument or alloca, then we don't need to scan.
   Previously we would only avoid the scan if the alloca
   or byval was actually considered dead.
2. The dead store processing code is itself completely
   dead and didn't handle volatile stores right anyway,
   so delete it.  This allows simplifying the interface
   to RemoveAccessedObjects.

Performance optimization on ImmutableMap/ImmutableSet:

- Use a DenseSet instead of a FoldingSet to cache
canonicalized nodes.  This reduces the overhead
of double-hashing.

- Use reference counts in ImutAVLTree to much
more aggressively recover tree nodes that are
no longer usable.  We can generate many
transient nodes while using add() and remove()
on ImmutableSet/ImmutableMaps to generate a final
set/map.

For the clang static analyzer (the main client
of these data structures), this results in
a slight speedup (0.5%) when analyzing sqlite3,
but much more importantly results in a 30-60%
reduction in peak memory usage when the analyzer
is analyzing a given function in a file.  On
average that's about a ** 44% reduction ** in the
memory footprint of the static analyzer.

Make @llvm.invariant.start not be readonly, so that it has side-effects. This
unbreaks test/Transforms/InstCombine/invariant.ll which was broken by r120382.
This is a fix-forward to do what I think Chris intended.

Stub out a new LiveDebugVariables pass.

This analysis is going to run immediately after LiveIntervals. It will stay
alive during register allocation and keep track of user variables mentioned in
DBG_VALUE instructions.

When the register allocator is moving values between registers and the stack, it
is very hard to keep track of DBG_VALUE instructions. We usually get it wrong.
This analysis maintains a data structure that makes it easy to update DBG_VALUE
instructions.

clean up handling of 'free', detangling it from everything else.
It can be seriously improved, but at least now it isn't intertwined

Add correct encoding for "bl __aeabi_read_tp". However, the asm matcher isn't
able to match this yet.

Teach basicaa that memset's modref set is at worst "mod" and never
contains "ref".

Enhance DSE to use a modref query instead of a store-specific hack
to generalize the "ignore may-alias stores" optimization to handle
memset and memcpy.

my previous patch would cause us to start deleting some volatile

two changes to DSE that shouldn't affect anything:

1. Don't bother trying to optimize:

lifetime.end(ptr)
store(ptr)

as it is undefined, and therefore shouldn't exist.

2. Move the 'storing a loaded pointer' xform up, simplifying
  the may-aliased store code.

Fix the encoding of VLD4-dup alignment.
The only reasonable way I could find to do this is to provide an alternate
version of the addrmode6 operand with a different encoding function.  Use it
for all the VLD-dup instructions for the sake of consistency.
