R600/SI: Only create one instruction when spilling/restoring register v3

The register spiller assumes that only one new instruction is created
when spilling and restoring registers, so we need to emit pseudo
instructions for vector register spills and lower them after
register allocation.

v2:
  - Fix calculation of lane index
  - Extend VGPR liveness to end of program.

v3:
  - Use SIMM16 field of S_NOP to specify multiple NOPs.

ARM64: refactor NEON post-indexed loads & stores (MC).

Previously, LLVM had no knowledge that these instructions actually
modified their address register: fine if they never end up in CodeGen,
but when I'd rather like to write some patterns for them it becomes a
disaster.

The change is mostly straightforward, I think the most significant
design decision was to *always* put the address write-back first. This
allows loads and stores to be accessed more uniformly, for example
permitting the continued sharing of the InstAlias definitions.

I also discovered that the custom Decode logic is no longer needed, so
I removed it.

No tests, because there should be no functionality change.

The movslq is uneeded, but is present because of the trunc to i32 and then
sext back to i64 that the backend adds for vbroadcastss.

We can't remove it because it changes the meaning. The IR that clang
generates is already suboptimal. What clang really should emit is:

  %a4 = extractelement <4 x float> %a2, i64 %j

This patch makes that legal. A separate patch will teach clang to do it.

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.

10 years ago[LCG] Fix a bad bug in the new fancy iterator scheme I added to support
Chandler Carruth [Thu, 1 May 2014 10:41:51 +0000 (10:41 +0000)]
[LCG] Fix a bad bug in the new fancy iterator scheme I added to support
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.
