Cleanup and augment string handling based on https://github.com/mono/mono/pull/15522.

1. When comparing strings, check pointer equality.
Faster when they match, slower when they do not.

2. Provide string lowercasing into a provided buffer, which can equal
the input, to avoid extra malloc/free.

3. define G_STRING_CONSTANT_AND_LENGTH(x) (x), G_N_ELEMENTS (x) - 1
e.g. strncmp (foo, G_STRING_CONSTANT_AND_LENGTH ("version"))

[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.

We should always have an IR instruction associated with an IL offset, especially when that instruction is a bb_start since we will need to branch to it and resolve the IR instruction from the il_offset.

Cleanup x86_patch and amd64_patch. (mono/mono#16474)

* Cleanup x86_patch and amd64_patch.

amd64_patch has two incorrect looking probably unused cases.
 g_assert(0) and fix them.
 call and jmp indirect (one case)
 move reg RIP relative

x86_patch is large-ish inline macro.
Presumably for sharing with amd64, not inlining.
Restructure as an inline function, called once.
Try to make the code a little clearer also, with same functionality and efficiency
 (modulo the optimized perf of "if i == 4" vs. "if i")
i.e. speak of instruction_size and offset_size, not pos and boolean size.

Add to x86_patch the ability to patch jmp/call indirect,
as amd64_patch has, but which was incorrect.
This would seem useful for a later change (using "thunks"
to patch nearby data instead of patching aligned instructions,
indirect call/jmp vs. direct).

amd64_patch largely delegates to x86_patch.
One case asserts and delegates.
Move the assert to the x86 side, where an optimizing
compiler should know to remove it for x86 anyway.

Change some assert to g_assert.

Remove some unnecessary casts.

Fix an assert (https://github.com/mono/mono/pull/16471).

[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.

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.

confused because it really can't run in the forked process at all.

Unity looked similarly dead.

The key points making it dead were:

create_allocator:
  g_assert_not_reached() covering everything but local variables

mono_gc_get_managed_allocator:
  always returning NULL, killing a bunch of code
  after it

mono_gc_is_critical_method:

- Notice this is varyingly absent on x86, arm64, amd64, s390x.
  Subject of another PR maybe.

Perhaps this was to enable the debugger to be 32bit against a 64bit target
on a biarch system, so it could do a cross-process manipulation of these pages?
That makes some sense on Windows at least.
(32bit debugger cannot debug 64bit target as of Vista, but that is using the Win32
"hard" debugger API. Mono could do otherwise).

There remains amd64 mono-codeman.c define ARCH_MAP_FLAGS MONO_MMAP_32BIT left alone.
