by -enable-experimental-feature NonescapableTypes
on the Windows platform
These passes do nothing unless the above feature flag is enabled, so
the only reason to run the pass is to exercise SwiftCompilerSources
and catch invalid SIL.
These passes rely on fundamental SwiftCompilerSources abstractions
which have not yet been tested outside of the passes. They don't yet
handle all SIL patterns, and SIL continues to evolve. We would like to
can these issues quickly as we hit them, but only if we have a way of
reproducing the failure. Currently, we don't have a way of reproducing
Windows-arm64 failures.
Workaround for:
rdar://128434000 ([nonescapable] [LifetimeDependenceInsertion]
Package resolution fails with arm64 Windows toolchain)
These were always redundant. And there is no way to emit them
correctly for valid OSA when the original dependence scope is in the
caller.
