In the task-to-thread model, there are no threading mechanisms by which
work could be offloaded onto another thread. As such, callback based
asynchronous APIs which are not Swift async do not make sense.

Originally move when it was in the stdlib as _move was behind a keyword but we
moved it in front to allow for some testing. Now that we are going with a
keyword (which we can't leave in/deprecate) move it behind the move only
experimental flag until this gets through evolution.
I also updated the move function tests to show that this is working. As a nice
bonus, I was able to enable all of the tests also in a non-optimized stdlib.
The new intrinsic, exposed via static functions on Task<T, Never> and
Task<T, Error> (rethrowing), begins an asynchronous context within a
synchronous caller's context. This is only available for use under the
task-to-thread concurrency model, and even then only under SPI.
* Implement String.WordView
* Add isWordAligned bit
* Hide WordView for now (also separate Index type)
add bidirectional conformance
Fix tests
* Address comments from Karoy and Michael
* Remove word view, use index methods
* Address Karoy's comments

- #58975 switched many tests from XFAIL on linux to linux-gnu, so seven
fail on the Android CI and two natively. They are now explicitly excluded.
- #39605 added several C++ Interop tests, 11 of which fail on the Android CI,
so disable them for now.
- #42478 removed the @noescape attribute for the non-Android
SIL/clang-function-types tests, so I remove it for Android too.
- My pull #40779 moved the Swift pointer tags to the second byte, so
SILOptimizer/concat_string_literals.64 will need to be updated for that,
disabled it for now.
- Compiler-rt moved the directory in which it places those libraries for
Android, llvm/llvm-project@a68ccba, so lit.cfg is updated for that.
Using XFAIL won't work here because the tests pass on the iOS back deployment bots, resulting in a UPASS.
I was able to take a look at the test binary and rule out both codegen for `if #available(...)` and the optimizer as culprits so the next step is to check if `_stdlib_isOSVersionAtLeast()` is actually busted in the runtime libraries in older versions of macOS.
