138515df66 First draft of the practical guide to atomics.
This is mostly descriptive of the intended state once atomic load and store have landed.

74699fda15 I am the code owner for Clang's IR generation; this has been true
for awhile, but it's good to make this official.  

Just to be clear, Doug and Ted "elected" me to this position.

Might as well add myself to the credits list while I'm at it.

dccc03b242 Add the 'resume' instruction for the new EH rewrite.
This adds the 'resume' instruction class, IR parsing, and bitcode reading and
writing. The 'resume' instruction resumes propagation of an existing (in-flight)
exception whose unwinding was interrupted with a 'landingpad' instruction (to be
added later).

ff03048c13 LangRef and basic memory-representation/reading/writing for 'cmpxchg' and
'atomicrmw' instructions, which allow representing all the current atomic
rmw intrinsics.

The allowed operands for these instructions are heavily restricted at the
moment; we can probably loosen it a bit, but supporting general
first-class types (where it makes sense) might get a bit complicated,
given how SelectionDAG works.

As an initial cut, these operations do not support specifying an alignment,
but it would be possible to add if we think it's useful. Specifying an
alignment lower than the natural alignment would be essentially
impossible to support on anything other than x86, but specifying a greater
alignment would be possible.  I can't think of any useful optimizations which
would use that information, but maybe someone else has ideas.

Optimizer/codegen support coming soon.
