As the PR

https://github.com/dotnet/runtime/pull/44041

effectively decoupled OwningType from Method in MethodWithToken,
I believe we now need to include OwningType in the Equals check,
otherwise we may (and sometimes do) crash in the assertion failure
checking that OwningType matches between instances.

Thanks

We were setting an unaligned stack size to the MethodDesc of ILStub. The
lowest two bits actually overlap with two flags in the extended flags,
so the size is expected to be aligned at least to 4 to not to overwrite
the flags. On macOS arm64, the computed native stack size can be misaligned,
so this change adds explicit alignment before storing the stack size to
the MethodDesc.

* include first and top in compacting

* Convert to assert

* Revert "Convert to assert"

This reverts commit 7da1a8c7d910ad00bbc7b40314997f70960729a5.

Now that we're not retyping small structs, the existing transformation works
for methods returning small structs too.

Fixes #51138.

Add support to run libraries tests on windows. Examples of how to run the tests:

    .\build.cmd libs.tests -test -os browser
    .\dotnet.cmd build /t:Test /p:TargetOS=Browser src\libraries\System.Collections.Concurrent\tests
    .\dotnet.cmd build /t:Test /p:TargetOS=Browser /p:JSEngine="SpiderMonkey" src\libraries\System.Text.Json\tests

* Add support for adding RIDs to RidGraph during build

* Address code review feedback

* Ensure GenerateRuntimeJson runs before Pack

The pack task itself doesn't do anything but depend on a sequence of tasks.
As a result running a target `BeforeTargets="Pack"` actually runs after
the package is created, since dependencies run before BeforeTargets.

Sequence the target before GenerateNuspec instead.

* Only add target RID to the RID graph

Try to avoid traversing the return block list it it's not necessary.

Add a header comment.

No diffs.

We now have the necessary support in the runtime and arcade.

Fix issue with card marking stealing where getting a new chunk caused the "card" variable to go backwards. This caused an extra call to card_transition, which in turn caused cards to be cleared that should be set. The ultimate result is memory corruption.

Here are the conditions that cause the bug to surface:
- an object containing pointers that straddles a 2 MB boundary
- the objects contains just value types (i.e. no pointers) for at least 256 bytes after the 2 MB boundary
- there is a generation-crossing pointer afterwards in the same object
- but that is the only generation-crossing pointer in that 256 byte range

The bug comes about because of the following sequence of events:
- in mark_through_cards_for_segments, we scan an object at the end of a 2 MB chunk
- we encounter a pointer location that is already outside of that chunk (it belongs to card 2 in the next chunk)
- we call card_transition, which advances the card to the card of the pointer location (i.e., to card 2 in the next chunk)
- we realize that we need to get a new chunk
- when we get the chunk, we set the card to card 0 in the chunk
- we return to mark_through_cards_for_segments
- as the next chunk is adjacent to the current one, we continue processing the current object
- when we encounter the next pointer location in the object, we trigger a card_transition again
- this will erroneously not clear cards 0 and 1 because we think it there is a cross-gen pointer
- it will also reset the cross-gen generation pointer counter
- thus, if there are no other cross-generation pointers in the 256 bytes described by card 2, card 2 will be erroneously cleared
- having cards cleared erroneously ultimately leads to heap corruption

The fix simply makes sure the "card" variable doesn't go backwards in find_next_chunk.

It fixes the issue because it avoids the double card_transition.

It is safe because during iteration of a segment, the "card" variable must always increase. When we switch to another segment, it may decrease, but that is fine because in this case it will be re-initialized by the logic in mark_through_cards_segments.

* Generalize loop inversion

Starting with an experimental branch from @AndyAyersMS,
generalize the loop inversion `optInvertWhileLoop` code
to consider duplicating an entire conditional block, not
just a conditional block that contains exactly one JTRUE
tree. Since the JTRUE itself wasn't considered before in
the costing, bump up the maximum cost allowed by 2 to account
for that. (Note that there is a lot of room here for tuning
the cost/benefit analysis.)

Additionally, the code already bumped the allowed cost if the
condition tree contained calls to a shared static helper. Add
another boost if the tree contains array.Length expressions,
which are likely to be CSE'ed.

Loop inversion by itself doesn't buy much, but our downstream
phases, like natural loop recognition, loop hoisting, and loop
cloning, depend on an inverted loop structure with a zero trip
test.

There are many diffs, typically size regressions because we
are duplicating code. Some notable cases:
1. BenchI Puzzle. This was a motivating example, from #6569.
It ends up with multiple new CSEs and BDN shows a 24% run-time
improvement.
2. RegexRedux_5 and ReverseComplement_1 also report faster
3. On the contrary, FannkuchRedux_5 reports 23% slower. It appears
we create fewer CSEs and end up with a couple more instructions
inside some tight loops.
4. Other things typically seen in diffs: (a) removed null and
bounds checks, (b) additional CSEs, (c) loop alignment kicks in.

The loop matching at the stage inversion runs is lexical and very
simplistic, as it is before natural loop recognition. As a result,
for some loops, like multiple-condition `while` loops (e.g.,
`while (--digits >= 0 || value != 0)` in
`System.Number:UInt32ToDecChars`), the inversion ends up creating
some pretty weird flow. (That's actually not new to this change.)

I added a `COMPlus_JitDoLoopInversion` config to allow turning
off the phase to do experiments.

Here are the diffs for SPMI on the benchmarks:

--------------------------------------------------------------------------------

Additionally, I removed some dead "optimization enabling" code.

* Code review feedback: fix one condition

* Improve flowgraph xml/dot dumping

1. Decouple it from JitDump
2. Add some documentation, including a useful link to https://sketchviz.com/
3. Fix DUMP_FLOWGRAPHS Release build
4. Fix some xml dumping issues
5. Replace custom function pattern parsing with CONFIG_METHODSET ".contains" function
6. Make dot format the default (instead of xml)

Fixes #43712

* Code review feedback: use `getCalledCount`

* Avoid temporary array allocations in reflection

* Add nullability annotations

* Move some lazy property getters out of the hot path

* More factoring out common fast paths

* Comment cleanup - no functional changes

* Moved some function blocks around for clarity - no functional changes

* Pass span into native stack byref

* Knock max stackalloced ctor parameters back to 4

* Move all CheckConsistency logic inline

Since the finalizer thread runs async with the test, we need to
atomically decrement the static instance counter.

* Add support in comhost tooling to embed type libraries.

Sdk work will still be needed to enable developers to embed tlbs in their comhosts.

* Cleanup.

* PR feedback. Update validation to throw specific exception types for specific errors so the SDK can accurately report errors to the user.

* Fix some memory attributions

This doesn't change the memory stats greatly, overall.

* Formatting

Fixes https://github.com/dotnet/runtime/issues/51109.

* Remove CSE ifdefs

`FEATURE_ANYCSE` and `FEATURE_VALNUM_CSE` are always enabled, and
are expected to remain so, so remove the ifdefs.

* Formatting

As specified in https://github.com/dotnet/runtime/issues/44654 the minimum iOS/tvOS version we're targeting for .NET 6 is iOS 10.
Bump the versions used in our build scripts and RID graph to that and also add iOS 14.
