3a0161ac77 AMDGPU/SI: Annotate Loops with Constant Condition in SIAnnotateControlFlow pass.
Summary:
  It is possible that the loop condition can be a boolean constant (infinite loop,
for example). So we sould handle constant condition in annotating a loop. This
patch adds this functionality to support annotating constant condition.

9d32832ffb AMDGPU: Change control flow intrinsics to use amdgcn prefix
These aren't supposed to be used outside of the backend,
so there aren't any users to worry about.

3d5dddde47 AMDGPU: Remove implicit ilist iterator conversions, NFC
One of the changes in lib/Target/AMDGPU/AMDGPUMCInstLower.cpp was a new
one.  Previously, bundle iterators and single-instruction iterators
could be compared to each other (comparing on underlying pointers).
I changed a comparison from using `MBB->end()` to using
`MBB->instr_end()`, since both end iterators should point at the some
place anyway.

I don't think the implicit conversion between the two iterator types is
a good idea since it's fairly easy to accidentally compare to the wrong
thing (they aren't always end iterators).  Otherwise I would have just
added the conversion.

Even with that, no there should be functionality change here.

f020cb2f75 [PM/AA] Remove all of the dead AliasAnalysis pointers being threaded
through APIs that are no longer necessary now that the update API has
been removed.

This will make changes to the AA interfaces significantly less
disruptive (I hope). Either way, it seems like a really nice cleanup.
