[msan] Refactor default shadow propagation and origin tracking.

This change moves the code for default shadow propagaition (handleShadowOr)
and origin tracking (setOriginForNaryOp) into a new builder-like class. Also
gets rid of handleShadowOrBinary.

Provide some actual highlight bullets for Clang.

If anyone has better highlights (I'm obviously biased by the things that
I'm excited about) jump in and add them!

Delete a long-stale "if its ready" comment. All indications is that this
will look a bit different when we have time to get it ready to turn on,
and we won't likely need this reminder.

Add a rough draft of some content about the new SROA. I'll try to proof
read this and clean it up tomorrow, but hopefully it's a good
placeholder.

[msan] Origin stores and loads do not need explicit alignment.

Origin address is always 4 byte aligned, and the access type is always i32.

Remove a section that was in 3.1's notes.

Just give a shout if this was actually still important....

This patch improves the 64-bit PowerPC InitialExec TLS support by providing
for a wider range of GOT entries that can hold thread-relative offsets.
This matches the behavior of GCC, which was not documented in the PPC64 TLS
ABI.  The ABI will be updated with the new code sequence.

Former sequence:

  ld 9,x@got@tprel(2)
  add 9,9,x@tls

New sequence:

  addis 9,2,x@got@tprel@ha
  ld 9,x@got@tprel@l(9)
  add 9,9,x@tls

Note that a linker optimization exists to transform the new sequence into
the shorter sequence when appropriate, by replacing the addis with a nop
and modifying the base register and relocation type of the ld.

Add more reset methods to make all objects that the backend may use for outputting code have a reset, some are not used but were declared for completeness

This patch removes some nondeterminism from direct object file output
for TLS dynamic models on 64-bit PowerPC ELF.  The default sort routine
for relocations only sorts on the r_offset field; but with TLS, there
can be two relocations with the same r_offset.  For PowerPC, this patch
sorts secondarily on descending r_type, which matches the behavior
expected by the linker.
