Moves the sanitizer ui tests to the sanitizer directory and removes the
sanitizer prefix from tests file names similarly to how the sanitizer
codegen tests are organized.

Fixes typo (i.e., saniziter) in test file names.

Update the minimum external LLVM to 16.
With this change, we'll have stable support for LLVM 16 and 17.
For reference, the previous increase to LLVM 15 was #114148

* 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

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.

CFI: Fix error compiling core with LLVM CFI enabled
Fix #90546 by filtering out global value function pointer types from the type tests, and adding the LowerTypeTests pass to the rustc LTO optimization pipelines.

this was a pre-existing latent bug, we just didn't have any CI builders exercising it.
fixes the following errors:
```

Fixes #111184 by encoding ty::Generator parent substs only.

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 #89653.
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).
