The `VersionTuple` API was changed llvm/llvm-project
219672b8dd06c4765185fa3161c98437d49b4a1b to return `VersionTuple`
from `get*Version` rather than pass in major, minor, and subminor output
parameters. Update uses to the new API.
Note that `getMacOSXVersion` is slightly different in that it returns a
boolean while taking a `VersionTuple` output parameter to match its
previous behaviour. There doesn't seem to be any use that actually
checks this value though, so we should either update the API to return
an `Optional` and actually check it *or* remove the "failure" case and
return a `VersionTuple` like all the others.
Make sure that we add the appropriate rpaths so that the appropriate
_Concurrency back-deployment library can be picked up.
We don't need to update the Swift driver since it uses the C++ driver
as the source of truth to determine if the relevant rpath should be
added or not.
The triple name aarch64_32 does not actually name a valid platform. The
actual platform (and valid triple arch string, confusingly enough) is
arm64_32. Remap between the two to correct for this difference.

Commit the platform definition and build script work necessary to
cross-compile for arm64_32.
arm64_32 is a variant of AARCH64 that supports an ILP32 architecture.
Prebuilt-module directory now contains a SystemVersion.plist file copied from the SDK
it's built from. This patch teaches the compiler to remark this version and the SDK version
when -Rmodule-interface-rebuild is specified. The difference between these versions could
help us debug unusable prebuilt modules.
Some code paths that see target triples go through the frontend
without seeing the driver. Therefore, perform the same "simulator"
inference for x86 iOS/tvOS/watchOS triples also in the frontend,
to ensure that we remain compatible. Also make sure that
-print-target-info performs the appropriate adjustment.
The *-simulator target triples have been used consistently in tools for
several years to indicate simulator targets. Stop inferring the
simulator part, rdar://problem/35810403.
