3933fc0006 [android][test] Fix several tests on the Android CI
- #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.

839839f924 [cxx-interop] Rename enable-cxx-interop -> enable-experimental-cxx-interop.
Also removes the driver flag, this will now also always be guarded on `-Xfrontend`.

036361d1e4 [cxx-interop] Add SIL function representation cxx_method; Support extending C++ types.
There are three major changes here:
    1. The addition of "SILFunctionTypeRepresentation::CXXMethod".
    2. C++ methods are imported with their members *last*. Then the arguments are switched when emitting the IR for an application of the function.
    3. Clang decls are now marked as foreign witnesses.

These are all steps towards being able to have C++ protocol conformance.

fc3b3a1d71 [cxx-interop] Implement foreign reference types.
This is an expiremental feature to allow an attribute, `import_as_ref`, to import a C++ record as a non-reference-counted reference type in Swift.
