At this point it's very stable and expensive to run, so we should probably move it out.

Single-file is still tested in our unit tests, but these runs were mainly to test the
compatibility of APIs with single-file. We've found that the analyzer does a pretty good
job of verifying that without testing, and we still have verification via NativeAOT, which
I think is a superset of the testing as a whole.

* Add linux-musl entry for FALLBACK_HOST_RID

* Stay consistent about host vs. target

* Classify linux-musl agnostic of distro

This reduces memory usage for NonBacktracking to what it was before capturing support.

* Explicitly check for TTL expiration when using Ping utility

* Fixes

* Improve the implementation

For unused indirs off of local variables we produce GT_NULLCHECK nodes
on arm64. The "CheckLclVarSemanticsHelper" class considers indirs off of
local vars to be local var reads and record these as outstanding in this
debug check, expecting to see a later use. However GT_NULLCHECK is not a
value so we never find such a use.

It is not clear that it is correct to consider an indir off of a local
var to be an outstanding read in general, but it seems that we currently
do not see cases that trip this check, so leaving it in for now.

Fix #65307

Update the ConvertToGeneratedDllImport code-fix to support stripping out PreserveSig and transforming the signature when PreserveSig was set to true (#65169)

if the callee interface method is not generic, but the constained constraint
uses a generic var or mvar, do the indirect interface call.

* For StoreLoc prefer allocating a multireg local def in the same registers as src in src/coreclr/jit/lsrabuild.cpp

* Properly check for the last use of a field of a multi-reg local in LinearScan::BuildStoreLocDef() in src/coreclr/jit/lsrabuild.cpp

* relax the assert

* no call to `EnsureTlsDestructionMonitor` on unsetting a thread.

This is a follow-up of #64679 

I realized that one invocation of `clock_nanosleep` wasn't replaced with `g_clock_nanosleep`.

* Update library dependencies to the latest

* Update ILCompiler.Reflection.ReadyToRun.csproj

* Incorporate review feedback from
#64646

* Prevent trimming of unused CachingContext.Count method

* use correct syntax for nested types

* Use static abstract interface methods in Ssl/NegotiateStream adapters

* Remove unnecessary argument from a bunch of methods

It's only used to add duplicative information to an exception message, and in doing so it makes the async methods it's used in more expensive.

- For concatenations, we currently do two passes over its nodes: one that coalesces adjacent characters into strings, and one that coalesces adjacent loops.  This swaps the order so that we first coalesce adjacent loops.  We want to coalesce loops first so that we prioritize associating a One with an adjacent loop rather than with an adjacent string.  This is primarily beneficial later on for auto-atomicity.  Consider `a+ab` composed of a loop, a One 'a', and a One 'b'.  We're either going to make that into a loop `a{2,}` followed by `b` or into a loop `a+` followed by the multi `ab`.  We want to do the former, as then when we apply auto-atomicity to the `a{2,}`, we'll see that it's followed by something non-overlapping ('b'), and make the loop atomic.  In constrast, if we joined the `a` and `b`, then auto-atomicity for the `a+` would see it's followed by an `a` and it wouldn't be upgraded.
- Currently, the adjacent loop coalescing logic joins two individual One nodes with the same Ch value into a repeater.  That's actually a deoptimization, so this stops doing so.  We'd rather have `aa` be evaluated as a Multi of two characters rather than as an `a{2}` repeater, as we're able to apply better optimizations with multis, e.g. taking advantage of StartsWith for matching.
- Also in the adjacent loop logic, we're already checking for a loop followed by a one but we're not checking for a loop followed by a multi.  For the same auto-atomicity benefits discussed earlier, we want to shift any adjacent text from a multi following a loop back into the loop, as it makes it more likely we'll then be able to upgrade that loop to atomic. (We could also add logic for a multi followed by a loop, but the benefits there are less obvious.)
- When creating repeaters, we're actually better off creating multis, for the same reasons outlined earlier.  But we don't want to create massive strings in the super rare case where large repeaters for single chars are used, so we only do so up to a limit.
- When emitting generated code for a One repeater, which might be used to implement the required portion of other loops, emit it as a multi match for short enough repetitions.

Backports changes introduced in the polymorphic deserialization prototype. JsonConverter.RuntimeType is an implementation detail stemming from interface support in collection converters, that has leaked into the JsonTypeInfo model. Removing it makes the contract model cleaner and makes the infrastructure compatible with polymorphic deserialization.

* Remove the concept of fat dispatch tokens and fat type ids from 64 bit platforms
- Phase 1 of removing locking from interface dispatch generation for generic dispatch
- We no longer need these due to changes to remove AppDomains from CoreCLR
- Phase 2 will likely remove the MethodTableWriteableData structure and merge the contents into the normal MethodTable

It's not needed and avoids accidentally including this assembly in places where we don't want it.
