* Refactor how casts are VNed, part 1

Remove duplication between VNPairForCast
and VNForCast, route the former through
the latter.

Also change the debug output for casts.

No diffs for this commit.

* Refactor how casts are VNed, part 2

VN cast helpers just like casts.
This allows them to be folded.

In the past, this was dangerous because some of
the pessimization protected us from undefined
behavior in cases of out-of-bounds conversions,
but now we do not fold such cases anymore.

* Enable VN-based constant propagation for calls

This solves some of the regressions seen due to
now-missing CSEs of these helper calls evaluated
as constants by VN.

* Fix VNFuncs for MUL_OVF helpers

This fixes the test failures revealed by
the more aggressive constant propagation.

This is very similar to a bug that was recently
fixed where checked casts were treated as non-checked
and could be observed without the assertion propagation
changes as well, with the redundant branches optimization.

This change
* Unifies the genSetRegToImm and instGen_Set_Reg_To_Imm functions,
  removing the former. genSetRegToImm seems to be a variant that did not
  support relocations/handles, while the latter supported both. We now
  exclusively use the emitAttr to determine this. This was only a change
  in xarch since on ARM architectures the former function just forwarded
  to the latter.
* Generates lea more often for handle GT_CNS_INT nodes on x64.
  Previously the logic generated only lea when a relocation was
  *required*, which is only the case for prejit. In particular, all VSD
  calls load an indirection cell that can use lea instead of the longer
  mov encoding during runtime JIT, which results in a nice code size
  decrease.
* Changes ARM64 and ARM to handle byref-typed GT_CNS_INT nodes. This was
  fixed for xarch a few years back in
  52a8890d but that change was not made
  to ARM architectures.

Currently we apply an optimization for ARM architectures where we make
sure we do not duplicate instructions to compute the target address for
calls that involve indirection cells, instead loading it from the
indirection cell directly. We can apply this optimization for x64 VSD
and tailcalls that also use indirection cells. This decreases the size
of these calls.

I have also included a bug fix for ARM/ARM64: the optimization was only
enabled under FEATURE_READYTORUN which is not always defined (e.g. in
single-file scenarios).

This caused the if (del->method) slowpath to be always taken.

* Remove duplicate entries from dotnet --info

* Remove trailing slashes from globally registered locations as well

1. Remove testing workaround to upload to "test_collect" special
JIT-EE version number.
2. Fix one YML bug
3. Reduce superpmi replay pipeline timeout

[wasm][test] BrowserHttpHandler stream large responses with SetBrowserResponseStreamingEnabled (#60339)

testing for https://github.com/dotnet/runtime/issues/60287

Fix #52905

* Update SuperPMI CI automation

A number of changes:
1. Move the SuperPMI replay pipeline to the public instance, so it can be
triggered by GitHub PRs.
2. Rename SuperPMI collection scripts to contain "collect" in their names,
to distinguish them from the "replay" scripts.
3. Remove a lot of unused copy/paste cruft
4. Create a new azdo_pipelines_util.py script for all the CI scripts to depend
on, so they don't import the superpmi.py script, or each other.
5. Some changes to simplify the Python imports and be more consistent in imported
API usage.

* Fix python

* Fix python names

* For testing, upload spmi collection to "test_collect" location

Don't overwrite the existing collection

All shipped implementations of RC2 require the EffectiveKeyLength to equal
the key length, so stop plumbing it through and use the key length as appropriate.

Updated the blazor_scenarios.proj helix precommand to use ';;' instead of '%3b'

* [docs] Add LLDB debugging instructions for Mono running a runtime test

* Also add a note about building a single test

Fixed WaitForCancellationAsync to take into account both read and write cancellations. Fixed not aborting on finalization.

Fixes #58234
Fixes #60141

If we try to get the ALC of an assembly from the default context before the
managed default ALC object has been created, the native gchandle has a null
target.
Ensure it is not null by explicitly referencing the Default ALC.

* [metadata] Replace uses of MonoType:byref by a getter

Call `mono_type_is_byref_internal` instead of accessing the byref bit directly.

No functional change. (I hope).

This is in preparation for exploring alternative representations of ref types.

* Change mono_type_is_byref_internal to take a const argument

* Missed a couple byref reads

* rename mono_type_is_byref_internal -> m_type_is_byref [NFC]

* more missed byrefs

* revert unintended change

* Fix PC tests

* Fix https://github.com/dotnet/runtime/issues/29753

- introduce globalThis.INTERNAL and move all exported methods which we only use internally or for testing
- reduce BINDING and MONO exports to minimal scope necessary - as used by Blazor
- fix all internal usages in tests
- produce dotnet.d.ts and include it in the workload
- moved Module.config to MONO.config
- added mono_load_runtime_and_bcl_args into MONO export
- removed obsolete debugger test InvalidScopeId
- introduced INTERNAL.mono_wasm_set_main_args
- add mono_wasm_new_root_buffer, mono_wasm_new_root, mono_wasm_release_roots to the MONO interface

* Fix System.Numerics.Vectors tests on iOS and other FullAOT targets

Instead of using dynamic we can use explicit type checks which don't require runtime code generation.
Also fixed running just a subset of xunit tests on Apple targets in tests.mobile.targets.

* Disable tests that fail on x86 due to a Mono runtime asserts

See https://github.com/dotnet/runtime/issues/60347

On x64, when the crc32 instruction 2nd operand is a memory address
(such as for a static field), and that address is containable
(which normally doesn't happen, because the address will be above
the 4GB lower address space), then the instruction was being
improperly encoded.

* [interp] Change GC state explicitly

GC transitions are being called from the m2n wrapper and they expect a LMF to have been pushed. With interpreter however, the LMF is not pushed during the execution of the wrapper but as part of the native CALLI. This means we need to do the GC transitions at a later time, when the LMF is pushed. We detect the GC transition IL code in the wrapper and instead of emitting the actual code we mark a flag. This flag is checked during the CALLI operations.

* [interp] Remove check for gc unsafe state during exception checkpoint

We are always in gc unsafe once returning from pinvokes or icalls.
