Loop canonicalization now maintains pred edges. GC poll insertion was already
maintaining the edges but was rebuilding them anyways.

Now pred lists are never rebuilt.

Also revise `fgUpdateChangedFlowGraph` so that it no longer has the
ability to remove or rebuild.

Fixes #49030.
Also fixes #80772.

Fixes #47462 

**CoreCLR** This also makes some changes to CoreCLR to decouple EventPipe and startup hooks. Presently if startup hooks are disabled, `RuntimeEventSource.Initialize` is never called.  The PR makes the two features independent by moving runtime event source initialization out of the startup hook feature check.

* Implement startup hooks support in Mono

* Keep StartupHookProvider.ProcessStartupHooks under feature flag

* Don't catch/cleanup the exceptions from startup hooks.

* Add an ios simulator startup hook functional test

* Implement Android functional test

* Add WASM functional test

* Make a single managed startup method for CoreCLR

A common configuration for coreclr is event source enabled, startup
hooks disabled, so at least one managed call is inevitable.  Since we
have to call into managed no matter what, let the trimmer determine
what happens once we get there.

This is different from mono where published trimmed apps may have both
startup hooks and event source disabled.  In that case we would rather
avoid a managed call to an empty method early in startup.

* fix build and line damage

TreeLifeUpdater at most needs to flip 4 bits in two liveness sets when
it is called, however before this change it uses several full width
bitset operations to do this. This changes TreeLifeUpdater to do its job
in a much more direct way by updating the liveness sets directly.

jit-analyze no longer accepts comma-separated metrics after
https://github.com/dotnet/jitutils/pull/362, instead requiring each
metric to be specified separately on the command line.

* [mono][interp] Remove MINT_VT_ALIGNMENT

It serves no purpose nowadays. All vars are aligned to MINT_STACK_SLOT_SIZE.

* [mono][interp] Add 16 byte default alignment to optimized code

This will enable us to control alignment of Vector128 vars at compile time.

* [mono][interp] Add stack alignment for unoptimized code

For normal calls, we introduce a new opcode before the call that will move all the arguments to aligned stack location. When emitting the code for the call, we emit directly the aligned call args offset instead. Unoptimized code has its own opcodes that do moving of param, we tweak them to copy them into aligned location.

* [wasm] Enable dedup by default.

* [wasm] Enable symbol map for AOT tests too

* MonoAOTCompiler: Fix up the path for the output items if they had been

.. copied to `aot-in` for the compilation step.

Example:
- when using WasmDedup=true, we get the main assemblies in `publish`
directory after linking, but `aot-instances.dll` is in different directory.
- this causes `MonoAOTCompiler` to copy all of them to a temporary `aot-in` dir for compiling with `mono-aot-cross`.
- And when the output items are set, we get:

```
 Output Item(s):
     _WasmAssembliesInternal=
         obj/Debug/net8.0/browser-wasm/wasm/for-publish/aot-in/Debug_u4nbxx3i.gc5.dll
                 LlvmBitcodeFile=obj/Debug/net8.0/browser-wasm/wasm/for-publish/Debug_u4nbxx3i.gc5.dll.bc
```

- here the `ItemSpec` is incorrectly set to the temporary `aot-in` path
- which can cause build failures in the following build steps

* WBT: remove redundant case

This stress mode poisons all implicit byrefs before returns from the
method. GC pointers are nulled out and other parts of the structs are
filled with 0xcd bytes.

This should help expose incorrectly elided copies in the recently added
last-use copy elision optimization.

Fix #80731

Unlike seemingly all other ARM instructions, the set of instructions
marked by this PR actually write their result in the second operand
register instead of the first. This means we were incorrectly updating
GC info when emitting these instructions.

It allows compilation using msbuild.exe that is x86 by default

We now update pred lists during loop unrolling, rather than recomputing
them from scratch.

There are several parts to the fix: first, `optRedirectBlock' now has
a new ability to add pred references for the flow from a newly cloned
block, be it either to a remapped successor or a non-remapped successor.
Along with this we no longer copy over the block ref count in `CloneBlockState`.
These changes allow us to create the right pred links and ref counts in the
interior of a cloned subgraph.

Second, we now scrub block references from the original loop body blocks
instead of just setting their ref counts to zero.

Finally, we fix up references for exterior flow into and out of the unroll
complex.

Addresses one of the cases mentioned in #49030.

* [wasm] Set TrimMode=full for templates

* [wasm] Remove TrimMode=partial default setting

.. and set TrimMode=partial for library tests.

* [wasm] don't set TrimMode explicitly for template projects. it will default to full now

* call the helper methods directly to reduce overhead (important for small inputs)

* inline the helper that was supposed to be public into it's only caller

* [wbt] correctly add RunAnalyzers property to template projects

Follow-up for https://github.com/dotnet/runtime/pull/77704

The first argument to `AddItemsPropertiesToProject` is the project file

* Catch non-existent projectFiles even if there's nothing to add

dotnet publish does not allow publishing with an output path in the .NET
8 SDK. They failed this weekend's rolling runs so this change makes the
build scripts specify the project to build.

The default is currently opt-in. "DbgDisablePagemapUse=0" needs to be set to
enable the pagemap checking feature. It is opt-in because it is breaking createdump
testing against 8.0.
