* Change SuperPMI collection to not use altjit mechanism

The SuperPMI collection process interposes a "shim" JIT between the JIT and EE.
As it is inconvenient to physically replace the existing JIT, currently this
is done by enabling altjit compilation and setting `COMPlus_AltJitName` to the
name of the shim JIT. This creates other inconvenience, especially with the
new way of saving the altjit flag in the JIT flags, by requiring us to
force the altjit flags bit to not be set, and force unset all the altjit flags.
It also makes it inconvenient to collect and/or replay with an actual altjit.

Change this collection mechanism to use the newly restored `COMPlus_JitName`
variable to allow specifying the JIT, and use that to specify the SuperPMI shim.

In addition, do not record in the MC file the `COMPlus_EnableExtraSuperPmiQueries`
variable. This is only used during collections to attempt to make replays more
flexible, but we never want to tell the JIT during replay that this is set.

* Enable `COMPlus_JitName` for crossgen as well

For the RuntimeEventSource, this removes around 30K of allocation, though that's only ~3% of what gets allocated.

* optimize constructor of ElapsedEventArgs

* delete the old ctor

The --raw command-line option used to dump bytes prefixed with their RVAs for all structures except GC blobs, which were dumped with file offsets instead. This change fixes that inconsistency. It also fixes the size reported by x86.GcInfo, which determines how many bytes to dump. In addition I simplified ReadyToRunMethod's code to store just the GC blob's RVA and avoid the delegate allocation.

  iOS).
* Fix Solaris version in test with SDK's PlatformDetection.
  * only major version is needed.

* Implement Enviornment.WorkingSet for SunOS
Difference between Linux and SunOS procfs is that files in latter
contain binary data, so we need `read(2)` and cast into corresponding
struct. Redeclaring system structs in managed code is not ideal, as
they do change across the major versions of OS, which inevitably
requires recompilation of binaries and replicating them in C# as is
means additional/unnecessary maintenance of code.

* Don't wrap string literal const as nop for CoreRT.

It was probably an old workaround for another Jit bug, it is most likely fixed by now.

* Change `gtGetThisArg` not to return `nullptr`.

There was only 1 case where a null return was tolerated - for a tail call in `optAssertionGen` marked as virtual.
However, a transformed tail call is never a virtual, fix `fgMorphTailCallViaJitHelper` to unset virtual flag.

* Keep x86 tail call via jit helper as a virtual stub call.

Update breaking change number because doubly linked free lists use one additional bit in the method table pointer at the beginning of objects now.

Added a comment noting that gcDacVars->major_version_number that is set in gc.cpp is not actually checked by SOS, so SOS_BREAKING_CHANGE_VERSION should be updated if GC changes in a way that is incompatible with the existing SOS.

`assert()` will expand to a no-op if NDEBUG is defined, which can

destroyed before having had `operator bool` applied to it.

  of `ApplicationFileExtension`, `LibSuffix` instead of
  `LibraryFileExtension` and so on.

Running `xunit.console` from within the CoreRoot directory is problematic. It is executed by the shared runtime but has a full copy of the runtime and framework libraries next to it from which assemblies are getting loaded despite being for a pre-release test runtime.

Place the xunit assemblies under `<core_root>/xunit` and update the places that invoke it in local and Helix test runs.

The loaded tests do reference the xunit assemblies so they need to also be available in core_root for when the tests run (with the exception of the harness specific assemblies like xunit.console).

To enable on tests, you can pass MonoForceInterpreter=true as an extra MSBuild property.
