7f45d16cb2 Fix sanitize/cfg.rs test
* Move needs-sanitizer conditions to specific revisions that
  require them (otherwise the conditions are mutually exclusive
  with needs-sanitizer-kcfi and test is always ignored).
* Add missing revisions

7834ffbebe fix
this ICE was caused by `transform_ty`
in compiler/rustc_symbol_mangling/src/typeid/typeid_itanium_cxx_abi.rs
encountering an unevaluated const, while expecting it to already be evaluated.

add a regression test

CFI: Fix error compiling core with LLVM CFI enabled

Fix  by filtering out global value function pointer types from the type tests, and adding the LowerTypeTests pass to the rustc LTO optimization pipelines.

f7287b9a2c don't try to cross-compile sanitizer tests
this was a pre-existing latent bug, we just didn't have any CI builders exercising it.

fixes the following errors:
```

error in revision `opt1`: test compilation failed although it shouldn't!

004aa15b47 Add cross-language LLVM CFI support to the Rust compiler
This commit adds cross-language LLVM Control Flow Integrity (CFI)
support to the Rust compiler by adding the
`-Zsanitizer-cfi-normalize-integers` option to be used with Clang
`-fsanitize-cfi-icall-normalize-integers` for normalizing integer types
(see https://reviews.llvm.org/D139395).

It provides forward-edge control flow protection for C or C++ and Rust
-compiled code "mixed binaries" (i.e., for when C or C++ and Rust
-compiled code share the same virtual address space). For more
information about LLVM CFI and cross-language LLVM CFI support for the
Rust compiler, see design document in the tracking issue .

Cross-language LLVM CFI can be enabled with -Zsanitizer=cfi and
-Zsanitizer-cfi-normalize-integers, and requires proper (i.e.,
non-rustc) LTO (i.e., -Clinker-plugin-lto).
