[interp] Improve copy propagation (mono/mono#17154)
* [interp] Refactor tracking of stack/local values
Previously we had just an InterpInst* inside StackContentInfo, which was representing the instruction that pushed a certain local/value on the stack. This makes many things awkward, since an instruction is logically different from a value, that a local or a stack slot have. If we clear an instruction, it doesn't necessarily mean that the value that the instruction produced can't be stored on stack or in a local.
This commit creates a new structure StackValue, which holds the value.
* [interp] Generalize contents of StackValue
StackValue contains an opcode and some data to enable reconstruction of the value. For example instead of doing a LDLOC for a local, we can see if the local has a known value and use it instead (this could be a LDLOC from another local, whose value was propagated, or in the future a LDC). This will make more sense when we also start to track constant values.
Also decouple MOVLOC instructions from the cprop pass. They serve no purpose there. They are useful though when we do deadce, since we currently don't know how to kill instructions that change the stack.
* [interp] Handle dup opcode during copy propagation
* [interp] Avoid losing track of stack values for some opcodes
For some opcodes, that access stack values below the top of the stack, we were assuming they pop everything and then push the stack back, in order to prevent optimizing away instructions that pushed some of these values, since the original instruction expects those values to reside on the stack. We handle these instruction separately and keep track of the values of the stack, so we can further propagate the stack values, even though we currently can't optimize away those instructions.
* [interp] Propagate values for ctor arguments
* [interp] MINT_CASTCLASS no longer clobbers top of stack

In mono/mono@
6d2c77fb3373971b4c615a70fe43f3622e3c91d8 we changed the representation of
the runtimes that we will probe from a NULL-terminated array to a linked list.
Unfortunately we made a typo, and in the case where the caller of
mono_init_internal provided a runtime_version, we still picked
DEFAULT_RUNTIME_VERSION instead of the given runtime_version.
This is an issue for embedders like XA that use the "mobile" runtime - all
their assemblies are compiled with the "mobile" version number (2.0.5.0) but
Mono running with the default runtime configuration will remap to 4.0.0.0. As
a result, when there are references to 2.0.5.0 assemblies, the load requests
will be remapped to 4.0.0.0 which will never see the already loaded 2.0.5.0
assemblies, and we will fall back on the embedder's preload hook or filesystem
probing every single time. This is a performance fail.

[debugger] Properly close debugger thread when connection hangs
When we detach from the debugger, we reset the state by starting a new debugger thread (why don't we just use the existing thread?). As per commit https://github.com/mono/mono/commit/mono/mono@
540ef385faa230bc226c7a83bfabd0730520911e we should shut down the debugger thread when the connection drops. However, since that commit was acting as a Dispose command was sent instead, it would end up relentlessly spawning and closing new debugger threads up until the runtime is shut down. This commit makes sure we don't respawn once the connection hangs.

* Creating a new version of MOD_KIND_EXCEPTION_ONLY to support VsWin features, discussed with Joaquin Jares.
Because we don't have this functionality of get every other exception that is not specified, VsWin was getting every exception and filtering later. But this causes a slowness during the debugger because we stop all thread on each exception that we get, even if they are caught and we don't want to stop.

Inline TLS access. (mono/mono#16882)
The same functions are referenced by JIT and runtime.
The JIT uses cannot be inlined. The runtime can.
Since I could not get anything else to build and the change is simple and mechanical, now two sets of functions are provided, inline and extern. Extern just calls inline.
This PR appears to change all the uses, but it is only the JIT uses. The runtime ones just work and keep the old names.
We should also consider building desktop with LTO/LTCG, which would do all this automatically, smarter, more generally. A quick experiment shows it grows the runtime size, which is why I say desktop.

[interp] avoid exception checkpoint when in thread is in GC Safe state (mono/mono#16955)
[interp] avoid exception checkpoint when in thread is in GC Safe state
Usually the interpreter operates in GC Unsafe state. There is an exception however, and that is when it executes a `managed-to-native` wrapper in cooperative (or hybrid) suspend.
The wrapper does essentially:
1. enter GC Safe state via `mono_threads_enter_gc_safe_region_unbalanced`
2. call native function
3. exit GC state via `mono_threads_exit_gc_safe_region_unbalanced`
Usually upon return of a native function call, the interpreter would check for thread interruption and, if applicable, throw an exception. That, however, would mess with the GC state as the interpreter operates in GC Safe state at this moment.
Note that ignoring thread interruption at that point shouldn't be a problem, because after 3. the `managed-to-native` wrapper will check for thread interruption anyway.

[Coop] InterlockedCompare/Exchange (object/T) (mono/mono#16873)
* [Coop] InterlockedExchange (object and T), InterlockedCompareExchange (object and T).
- Usually intrinsified.
- Always?
- Avoid coop handles by manually always using ref to object.
- For efficiency on input, and efficiency wrt MonoError.
- For correctness on output (due to aliasing in the wrappers).
- To probably avoid assertion failure in runtime around icall marshaling of generics.
- Unclear on location.
* Balance parens in prints, so they are balanced in the code.
* Reduce local arrays from 16 to auto-sized 1.
* Update and reformat System.Threading.Interlocked signature recognition.
* Rename the generic again to "_T" (or "Generic"?) on the theory
that the aot-runtime.c signature check is too strict/incorrect,
but that if we loosen it, it is not clearly specific to the generic.
* Revise corlib version again.
* Bump API snapshot submodule

[arm64_32] make "Debug Mode" work on Watch series 4 with --interpreter (mono/mono#16865)
[arm64_32] make "Debug Mode" work on Watch series 4 with --interpreter
Main objective for reviewers: This PR shouldn't change anything for `arm64`.
Context: "Debug Mode" on the Apple Watch allows execution of regular machine code and thus is pretty similar to FullAOT on iPhone, i.e. it doesn't require bitcode, but _still_ doesn't allow `signal(3)` so cooperative suspend is required.
Apple Watch Series 4 and onward use an ARM64 chip, but with a different ABI, also known as `arm64_32`. This PR changes the AOT compiler and related trampolines so that the AOT compiler can generate all necessary code to run the interpreter on this target.
Changes:
--------------------------------------
[arm64_32] set register size to 8 in cross compiler too
-----------------------------------------
[machine] update `target_mgreg_t` definition
`SIZEOF_REGISTER` is usually the same as `TARGET_SIZEOF_VOID_P`, except when `MONO_ARCH_ILP32 is defined.
`target_mgreg_t` should represent the width of the hardware register, that is, `SIZEOF_REGISTER`.
---------------------------------------------
[arm64_32] fix AOT image layout
---------------------------------------------
[arm64_32] make trampolines bitwidth aware
* replace pointer loads/stores with bitwidth-dependent macro
* reflect `specific` trampolines so that only two instructions are used for ILP32, since the related pair in the data page only needs 2 * 32bits too
* replace some `sizeof (target_mgreg_t)` with `TARGET_SIZEOF_VOID_P` (former is hardware register size, latter is pointer size)
---------------------------------------------
These regression tests are _not_ passing: https://github.com/mono/mono/issues/16864 Also some of monotouch-tests are crashing, see https://github.com/mono/mono/issues/16819
