[Coroutines][5/6] Add coroutine passes to pipeline
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
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).
