There has been universal support for merging it in, so lets do it.  Please start
by commiting the llvm part (i.e. lib/Target/ARM64, tests, etc).  We should have
a similar discussion on cfe-dev to get those changes reviewed, and commit the
clang pieces when that settles out.

The libc++, compiler_rt, and lldb piece should be separately reviewed and
explained before they go in.

Thanks Bob (and everyone who worked on the apple arm64 backend!)

Is the LLDB patch missing? I only see libc++, compiler-rt, LLVM, and
Clang patches.

Cheers,

Tim has volunteered to commit the initial changes tomorrow. Things should be a
little quieter then because its a Saturday. I’m rebasing the changes one more
time now.

Sounds great, thank you Tim!

We have a patch for LLDB but it is combined with a variety of other changes.
Someone will have to go through and sort those out first.
