[NFCI][Coroutines] update tests to autogenerated formatting (#178358)

The best practices for llvm is to use the update scripts instead of
manually writing tests, so update tests to use the script, where the
change is subjectively minor. These tests are necessary to update again
for my branch to change CoroFrame to using all opaque ptradd instead of
typed gep and alloca. Currently that pass uses whatever random type the
largest non-overlapping alloca happened to have when the other alloca
were re-written to replace be replaced by it. In this future branch, it
will all just uses simple ptrgep operations. This is part of an
on-going series of PRs to fully deprecate using getAllocatedType and
replace it with getAllocationSize, because it had no semantic meaning,
just like typed pointers were deprecated for opaque pointers.
