- For some reason, after moving the functions out of the Thread class, YieldProcessorNormalized was not getting inlined anymore. It seems to be important to have it be inlined such that the memory loads are hoisted out of outer loops. To remove the dependency on the compiler to do it (even with forceinline it's not possible to hoist sometimes, for instance InterlockedCompareExchnage loops), changed the signatures to do what is intended.

Add span-based Guid.{Try}Parse{Exact} methods (#14062)
This commit does two things:
- Changes the existing Guid.{Try}Parse{Exact} methods to work in terms of spans rather than strings.
- Then adds new overloads that accept spans and that uses the same underlying span-based support.
Due to the first change, performance actually improves for several of the guid formats, in particular due to substring allocations that are no longer incurred. For example, this program:
```C#
using System;
using System.Diagnostics;
class Program
{
static void Main()
{
var sw = new Stopwatch();
const int Iters = 1000000;
Console.WriteLine("Pattern\tBytes\tTime");
foreach (string pattern in new[] { "D", "B", "P", "N", "X" })
{
string input = Guid.NewGuid().ToString(pattern);
Guid.Parse(input);
long a = GC.GetAllocatedBytesForCurrentThread();
sw.Restart();
for (int i = 0; i < Iters; i++) Guid.Parse(input);
sw.Stop();
a = GC.GetAllocatedBytesForCurrentThread() - a;
Console.WriteLine($"\"{pattern}\"\t{a / Iters}\t{(int)(sw.Elapsed.TotalMilliseconds / Iters * 1000000)}ns");
}
}
}
```
on my machine previously output:
```
Pattern Bytes Time
"D" 0 218ns
"B" 0 217ns
"P" 0 210ns
"N" 168 388ns

Sane spill weights
The existing spill weight computation is comparing non-normalized bbWeight to normalized lvRefCntWtd, and is also using the weight of whatever the last block turns out to be (often EH zero-weight block) for the `RefTypeParamDef`s.
The straightforward fix resulted in regressions:
- It turns out that it is useful to give extra weight to tree temps, as all their references are very localized.
- Also, it is helpful to reduce the relative weight of a lclVar if it has already been spilled.
As is often the case, more tuning would be useful, but this is a more sane algorithm.

fd91ee1fa23f35130f576c19dfaf35934dc2ce24 is causing @benaadams thread pool perf test (https://github.com/benaadams/ThreadPoolTaskTesting) to hang due to a missed thread request. Somehow wsqActive is ending up at zero while there is a work item in the queue and with no pending thread requests. I don't understand how yet.
99db31c41d5057e08cc4701c79f11246b9191a9b appears to have a potential issue because the order of MarkThreadRequestSatisfied and Dequeue are reversed. For instance, assuming a proc count of 1:
- Initial state: 1 work item enqueued, 1 thread request
- T1 Dispatch: dequeues a work item and requests a thread (0 work items, 1 thread request)
- T1 Dispatch: sees no more work items, returns
- T1 calls Dispatch again due to its own thread request
- T1 Dispatch: After Dequeue (which saw 0 work items) and before MarkThreadRequestSatisfied:
- Current state: 0 work items, 1 thread request
- T2 enqueues a work item, sees 1 thread request and does not request a thread (1 work item, 1 thread request)
- T1 Dispatch: MarkThreadRequestSatisfied decrements thread requests (1 work item, 0 thread requests)
- Now after T1 returns, it won't wake up again but there is still one work item in the queue

Update BenchmarksGame benchmarks to latest
For each benchmark, grab the current best C# .NET entry, and also grab
the current best serial implementation (since these are easier to work
with from the benchmarking perspective).

JIT: Use AllocObj for box allocations (#13988)
Model box object allocations using the AllocObj tree node. Update
the box deconstruction utility to compensate.
Also set the OMF_HAS_NEWOBJ flag when we generate Box IR; this both
fixes an oversight from before and is a necessary step to trigger the
morphing of AllocObj into a helper call.
No diffs.
Closes #13905.

Disable tiered compilation for dynamic methods
Fixing an oversight from earlier, tiered compilation isn't designed to handle dynamic methods yet because of their limited lifetime. There may be other issues but a basic one would be having the method get collected while its MethodDesc is in the tiered compilation queue which results in use after free memory issues.

Improve ReaderWriterLockSlim scalability (#13243)
Improve ReaderWriterLockSlim scalability
Fixes #12780
The _myLock spin lock runs into some bad scalability issues. For example:
- Readers can starve writers for an unreasonable amount of time. Typically there would be more readers than writers, and it doesn't take many readers to starve a writer. On my machine with 6 cores (12 logical processors with hyperthreading), 6 to 16 reader threads attempting to acquire the spin lock to acquire or release a read lock can starve one writer thread from acquiring the spin lock for several or many seconds. The issue magnifies with more reader threads.
- Readers and especially writers that hold the RW lock can be starved from even releasing their lock. Releasing an RW lock requires acquiring the spin lock, so releasers are easliy starved by acquirers. How badly they are starved depends on how many acquirers there are, and it doesn't take many to show a very noticeable scalability issue. Often, these acquirers are those that would not be able to acquire the RW lock until one or more releasers release their lock, so the acquirers effectively starve themselves.
Took some suggestions from @vancem and landed on the following after some experiments:
- Introduced some fairness to _myLock acquisition by deprioritizing attempts to acquire _myLock that are not likely to make progress on the RW lock
- Limited spinning in some cases where it is very unlikely that spinning would help
