[interp] Transform ldloc/stloc pairs to a movloc instruction (mono/mono#16546)
* [interp] Add stack information for each instruction
For each instruction PopN indicates how many values from the top of the stack are used by the instruction. PushN signals how many values are pushed back. These are also used to prevent values from the stack being optimized out, since they might still be used by an instruction. VarPop and VarPush mean that the number is not constant, so we need to inspect the data fields of the instruction (typically for an imethod or csignature) to figure out the stack usage.
* [interp] Convert ldloc/stloc pairs to movloc
The movloc instruction operates directly on locals. This is faster due to avoiding dispatch and stack indirection. More important is that it makes it easy to do copy propagation of locals and it has no stack usage, which means that it could even be killed if the destination local is no longer referenced (as well as STLOC_NP). In the future we could reuse this mechanism of tracking the value of a stack slot to do constant propagation and kill even more instructions (we might need to have _IMM versions of opcodes for this to work).
* [interp] Enable disabling of interp optimization
* [interp] Add time tracking stat for cprop optimizations
* [interp] Move stloc.np transformations to the cprop pass
It makes more sense to do such transformations here and we also don't want transformations in the generate phase prevent us from detecting alternative transformations when running the full pass.
* [interp] Add counter for instructions that were optimized away
* [interp] Make it explicit that we are dealing with IR code
It can be confusing in verbose output.

[mini] publish global patches after JitInfo has been added (mono/mono#16589)
[mini] publish global patches after JitInfo has been added
Fixes https://github.com/mono/mono/issues/14080
Consider the following example:
```csharp
static void CommonCallTarget () { }
static void TailA () {
tailcall CommonCallTarget ();
}
static void TailB () {
tailcall CommonCallTarget ();
}
```
Since `TailA` and `TailB` are tailcalling into `CommonCallTarget`, the resolution at patch-time is a bit tricky, that is, since it's a jump-like instruction the patching machinery won't know where it was called from. That's why we maintain a global hashtable `jump_target_hash` where each jump-site is signed up to be patched. At patch-time we know the target method (in the example `CommonCallTarget`), but since we don't know where we are coming from, we will just apply all patches for that target.
This works since ages, so why did it crash on arm64 sometimes?
When the patching happens, we check if the displacement between jump-site and target fits into it (24bit). If not, which happens not very often, we have to allocate a _thunk_:
https://github.com/mono/mono/blob/mono/mono@
36296ce291f8a7b19de3eccb7a32c7e4ed9df8f2/mono/mini/mini-arm64.c#L928-L942
So instead of jumping to the target directly, we'll branch to the thunk. This is a little trampoline that loads the full address of the target and then finally branches to it. This one will live close-by the jump-site, because during compilation we will reserve specifically for that scenario some space after the generated code. For this, however, we need the JitInfo of the jump-site. And that's where the origin of the race is. Let's say:
* Thread A compiles `TailA`, and then jumps into it. Thus one patch point is in the `jump_target_hash`.
* Now Thread B compiles `TailB`, registers the patch point but has _not_ yet registered its JitInfo.
* Then Thread A continues, does the tailcall into `CommonCallTarget`, enters the patching machinery, which sees two patches. Now assume when applying the patch for `TailB` the displacement is too large, thus it tries to allocate a thunk but can't find the relevant JitInfo for it that it needs to emit the thunk. So it crashes as reported in https://github.com/mono/mono/issues/14080
As far as I can tell this only affects ARM64, ARM and PPC.

[configure] remove autodection of llvm-config in $PATH
Instead `./autogen.sh --with-llvm=<path>` should be used if a build from `external/llvm` is not preferred.
The old behavior was confusing when a `llvm-config` is on `$PATH`, which can be the case when you have LLVM packages installed on a Linux distribution. It picked that up when `./autogen.sh --enable-llvm` was used.

Read only function pointers (MonoThreadInfoRuntimeCallbacks). (mono/mono#16545)
Read only memory is preferred, for efficiency and security.
Even if it requires relocation first.
If the runtime is loaded in more than one process, physical pages can be shared (at least on Windows, where the kernel does the relocation).
If there is memory corruption, writes to here will sigsegv/accessviolate.
The older code also copied the pointers. For lifetime purposes that could be useful, but generally is not. i.e. they live with the code they point to.
Writable function pointers are also particularly targets for attackers.
There's been tons of defenses put around them through the years.
Read only ones are not vulnerable -- unless the attacker escalates and calls mprotect first.
When there is a JIT, arguably there is just tons of attack surface.
But there is also AOT.
Structs of function pointers are usually read only in the wider world.

ves_icall_Mono_Runtime_EnableCrashReportingLog is called. That function is
only expected to be called by apps that explicitly want progress reports from
MERP when it's collecting a crash report. But we want the mono-hang-watchdog
to execute for all mono crashes (when crash reporting isn't ifdef'd out).
Also if we try to exec mono-hang-watchdog and fail for some reason, print a
nice message and then exit. We used to call g_assert_not_reached which would
kick off another MERP of the _forked child process_ which would then get
confused because it really can't run in the forked process at all.

Perhaps this was to enable the debugger to be 32bit against a 64bit target

That makes some sense on Windows at least.

[interp] Remove unnecessary recomputation (mono/mono#16509)
Seems to have been added by mistake in https://github.com/mono/mono/pull/16317, which was meant just to remove the locals variable from InterpFrame.

[interp] Error handling refactor (optimize non-exception path) (helps clang save stack) (mono/mono#16371)
While working on stack reduction, I believe I found that
the compiler could not tell how THROW_EX and/or NULL_CHECK terminate.
That is, essentially, the success paths preserve volatile registers.
They do not have to be spilled/filled.
This tweak should make it clearer to the compiler, optimized common paths, and not slow down uncommon paths.
This also cleans it up a little and reduces macro expansion, and then possibly should allow for reinlining what is now used only once.
Also add some const so it can be casted away less.
Believed to save 32 bytes of stack with Linux/amd64/clang, nothing for gcc.
And a nice cleanup.

Fix multiple SGEN_LOG to correctly scale elapsed time in usec. (mono/mono#16485)
Several SGEN_LOG entries logged usec based on result returend from TV_ELAPSED.
On SGEN's implementation of TV_ELAPSED, the result is not scaled to usec
but returned as 100ns ticks. This was not handled correctly by SGEN_LOG,
but other measures, like profile counters and SGEN binary protocol handles
it correctly.
Fix will adjust the SGEN_LOG calls currently presenting usec to correctly
scale the result. Fix also adds one additional logging measuring total
amount of time spend scanning thread data.

CodeManager cleanup: (mono/mono#16468)
- Chunks do not need flags, only codemanagers do.
- Sort by size to minimize padding for alignment.
- Booleans only need one bit.
- Chunk is not spelled chunck.
- Suggest foo accessors be named foo() and set_foo(), not get_foo() and set_foo().
i.e. the more common "get" is implied.
- Allow free(0) w/o initialization.
