[Coroutines][5/6] Add coroutine passes to pipeline
Summary:
Depends on https://reviews.llvm.org/D71901.
The fifth in a series of patches that ports the LLVM coroutines passes
to the new pass manager infrastructure.
The first 4 patches allow users to run coroutine passes by invoking, for
example `opt -passes=coro-early`. However, most of LLVM's tests for
coroutines use an option, `opt -enable-coroutines`, which adds all 4
coroutine passes to the appropriate legacy pass manager extension points.
This patch does the same, but using the new pass manager: when
coroutine features are enabled and the new pass manager is being used,
this adds the new-pass-manager-compliant coroutine passes to the pass
builder's pipeline.
This allows us to run all coroutine tests using the new pass manager
(besides those that use the coroutine retcon ABI used by the Swift
compiler, which is not yet supported in the new pass manager).

pipeline with a pass, and the minimal context of pass managers will be
built around the entire specified pipeline. This makes the common case
for tests super easy:
./bin/opt -passes=instcombine,sroa,gvn
But this won't introduce any of the complexity of the fully inferred old
system -- we only ever do this for the *entire* argument, and we only
look at the first pass. If the other passes don't fit in the pass
manager selected it is a hard error.
The other interesting aspect here is that I'm not relying on any
registration facilities. Such facilities may be unavoidable for
supporting plugins, but I have alternative ideas for plugins that I'd
like to try first. My plan is essentially to build everything without
registration until we hit an absolute requirement.
Instead of registration of pass names, there will be a library dedicated
to parsing pass names and the pass pipeline strings described above.
Currently, this is directly embedded into opt for simplicity as it is
very early, but I plan to eventually pull this into a library that opt,
bugpoint, and even Clang can depend on. It should end up as a good home
for things like the existing PassManagerBuilder as well.
There are a bunch of FIXMEs in the code for the parts of this that are
just stubbed out to make the patch more incremental. A quick list of
what's coming up directly after this:
- Support for function passes and building the structured nesting.
- Support for printing the pass structure, and FileCheck tests of all of
this code.
- The .def-file based pass name parsing.
- IR priting passes and the corresponding tests.
Some obvious things that I'm not going to do right now, but am
definitely planning on as the pass manager work gets a bit further:
- Pull the parsing into library, including the builders.
- Thread the rest of the target stuff into the new pass manager.
- Wire support for the new pass manager up to llc.
- Plugin support.
Some things that I'd like to have, but are significantly lower on my
priority list. I'll get to these eventually, but they may also be places
where others want to contribute:
- Adding nice error reporting for broken pass pipeline descriptions.
- Typo-correction for pass names.
