* [netcore] Remove ves_icall_System_Runtime_InteropServices_Marshal_PtrToStringUni and _len icalls.
They are implemented in C#.
The C# is equivalent to the C, and could be used for classic runtime, except for the treatment of large/negative lengths.
* Remove a few more icalls.
Instead of ifdef and leaving them uncompiled when compiling netcore,
declare them and put asserts in them.

16byte stack pointer alignment is only required in certain places by the ABI, so the assumption that it holds all the time is wrong (though, it passed CI 😅). We have to setup the frame properly, i.e. we have to ensure the stack pointer is properly aligned. That's what we have done previously too.

In most cases, no `.dll.config` file exists and so it probes this
macOS-looking path:
/Users/builder/jenkins/workspace/archive-mono/2019-10/android/release/sdks/out/android-x86-release/etc/mono/assemblies/FormsViewGroup/FormsViewGroup.config
It looks like this is happening because nothing in Xamarin.Android
calls `mono_set_dirs` or `mono_set_config_dir` and so it falls back to
using `MONO_CFG_DIR`. `MONO_CFG_DIR` is set to a path on the build
machine.
Even if Xamarin.Android *did* call `mono_set_config_dir`, the code
appends `mono/assemblies`:
cfg = g_build_filename (cfg_dir, "mono", "assemblies", aname, cfg_name, (const char*)NULL);
So it doesn't seem useful to use this fallback at all, there would
never be a file found.
I wrapped the appropriate code in `#ifndef TARGET_ANDROID` blocks.

[sgen] Don't trigger collections during allocation of thread objects (mono/mono#17970)
Allocation of thread objects usese the mono_object_new_mature API. These objects are allocated before the thread is finished attaching to the runtime. This means that a collection can happen on an unattached thread as well as all its callbacks, which is a counter-intuitive behavior.
On android this is problematic because at the end of the SGen collection we need to call the java collection, which needs to have the thread attached. This could probably be fixed instead from the Xamarin.Android side, but this approach seems simpler and saner.

Refactor Monitor to eliminate near identical duplicated code. (mono/mono#17964)
The only difference in the copies, was that one had an infinite timeout
so implied TRUE result unless interrupted.
Where the other copy had a timeout and could return FALSE as a result.
They both used the same underlying, with timeout, so it wasn't really an optimization,
just duplicated code.
Also there is subtelty around having a return value or an out parameter.
That is carefully preserved.
Also, coop is fixed, by creating a frame only in a slow path.
Presumably creating a thread is quick and stateless enough such that this
is not too late.

[threadpool] Decrement max_working when worker times out (mono/mono#17927)
[threadpool] Decrement max_working when worker times out
The corresponding code in CoreCLR:
https://github.com/dotnet/runtime/blob/mono/mono@
bf88f146412d1e2d41779422337184a802f186c9/src/coreclr/src/vm/win32threadpool.cpp#L2156-L2164
The issue is that counter._.max_working is only ever changed by:
1. the monitor_thread when it detects starvation (increment by 1).
2. the hill climbing algorithm (increment or decrement).
Creating a periodic load of creating many workers at once followed by a minute
or more of quiescence increases the variable worker.counters._.max_working in
monitor_thread(). Once that counter matches worker.limit_worker_max,
monitor_thread() keeps looping without unparking or creating a thread, even
though the actual number of threads/workers is small. If the existing threads
are all waiting on work that needs a new thread, then a deadlock occurs.
With this change, when a parked worker times out, it will lower max_working to
the number of active (working + parked + starting) threads minus itself (but no
less than limit_worker_min). As a result, monitor_thread will only increment
max_working as long as none of the already running workers are timing out.
Attempt to address https://github.com/mono/mono/issues/17833

Also allow monitor_thread to start workers if there aren't enough active, even if the max worker limit has been reached.
Work around a pathological condition where the work_item_count is non-zero, and
the max_working limit has been reached, but the number of active threads is
still below the max. In that case, unpark some workers and start some new
threads.

[amd64] do not stack allocate on the application stack for the transtion from alstack handling (mono/mono#17922)
### Backstory
This test is failing in the interpreter (ONLY on Debian9/amd64. Not Ubuntu/amd64. Not macOS/amd64):
https://github.com/mono/mono/blob/mono/mono@
0fed03ed63ed4ea742c4511d8edc3bc1c6f4044f/mcs/class/Mono.Debugger.Soft/Test/dtest.cs#L2484-L2499
Where the debuggee is just some unsafe code that tries to read from unmapped memory, thus causing a segfault.
So the test expects the runtime to send a CRASH event via the managed debugger interface. This happens very late in the crash handling machinery:
https://github.com/mono/mono/blob/mono/mono@
0fed03ed63ed4ea742c4511d8edc3bc1c6f4044f/mono/mini/mini-posix.c#L1105
However, the runtime would never reach that, because it silently crashes when calling `backtrace`:
https://github.com/mono/mono/blob/mono/mono@
0fed03ed63ed4ea742c4511d8edc3bc1c6f4044f/mono/mini/mini-posix.c#L939
At the point where the SIGSEGV happens, the native stack trace looks like this:
```
Thread 1 "mono-sgen" received signal SIGSEGV, Segmentation fault.

```
Stepping into the crash handling machinery, the picture looks a bit different:
```
Thread 1 "mono-sgen" hit Breakpoint 1, altstack_handle_and_restore (ctx=0x7fffffffd2d0, obj=0x0, flags=0) at exceptions-amd64.c:871
871 {

%2 0x0000000000000000 in ?? ()
```
So it looks like we messed up in the transition from altstack back to the program stack.
### The fix
The problem is that `backtrace` consults the unwind information emitted at the point where SIGSEGV happens in `interp_exec_method_full ()`. However at that given program code, there is no function call that allocates space to pass arguments on the stack. Still, we massage the stack to do that in the signal handler, which does not add up with the emitted unwind information by the C compiler.
Note that without the fix, crashing in `backtrace` is the worst case. In other cases we might (1) get still a correct stack trace, or (2) we get a wrong stack trace, and `backtrace` will not crash. So this PR might improve the crash experience overall.

[WIP] Make debugger agent startup faster (mono/mono#17898)
Mono SDB's debugger agent takes a `host:port` parameter to specify the host and
port on which to listen for debugger connection. `host` is passed, via
`mono_get_address_info`, to the `getaddrinfo(3)` standard library call which
does the job of translating the name to the IP address. However, there's no
special treatment for situations when `host` is already an IP address. In this
case `getaddrinfo` takes a lot of time to perform at least two DNS lookups (if
there's just a single DNS server configured) which will time out as the IP
address in `host` will not be resolved by any of the servers.
`getaddrinfo` takes a "hints" parameter where caller can specify some
information about the `host:port` pair to make the lookup faster/easier.
However, Mono doesn't specify the address family in the `hints` parameter, thus
forcing the slow path of DNS lookups on `getaddrinfo`.
This commit adds a new hint named `MONO_HINT_NUMERIC_HOST` (which maps to
`AI_NUMERICHOST` for `getaddrinfo`) which will allow, if set, `getaddrinfo` to
take a faster route in address discovery. Debugger agent will, in most cases,
get an IP address to instead of host name so we call `mono_get_address_info` up
to 3 times (IPv4, IPv6 and unspecified) in order to make the lookup faster.

`mono_class_array_element_size` gives us the size of the provided MonoClass if it would be an array element. But here we want the element size of a given array's MonoClass. That's what `mono_array_element_size` is returning.

Which is then used later to compute the size to memset in order to clear the content of an array. If it's larger than it should be, then this will cause memory corruption. For example this would crash eventually:
```csharp
using System;
using System.Collections.Generic;

d.Clear ();
}
}
}

[debugger-agent] Fix CMD_VM_ALL_THREADS returning wrong value due to unitialized variable (mono/mono#17847)
`remove_gc_finalizing` wasn't initialized so its value is undefined.
The `count_thread_check_gc_finalizer()` function only sets it in some cases so we could end up with the variable having an undefined (and probably not 0) value.
This resulted in the returned thread count from the debuggee being wrong because we'd decrement `count` even though we shouldn't.

[llvm] Use explicit null checks with LLVM. (mono/mono#16954)
* [llvm] Use explicit null checks with LLVM.
When the LLVM backend is used for a method, explicit null checks will
unconditionally be used at the mini IR level. We had previously used
implicit null checks at the mini IR level combined with llvm-volatile
loads and stores to avoid mis-optimization of the generated code.
During AOT compilation, LLVM's `ImplicitNullChecks` pass is enabled.
This conservatively elides these explicit null checks. This pass only
modifies branches tagged with `make.implicit` metadata.
Null check branches are now tagged with `make.implicit` metadata, with
three exceptions:
1. For platforms with backends that do not support zero page fault
handling, null check branches are not tagged with `make.implicit`.
2. This commit also adds a `MONO_DEBUG` option:
`llvm-disable-implicit-null-checks`. When it is enabled, null check
branches are not tagged with `make.implicit`.
3. This commit alters the behavior of the `explicit-null-checks`
`MONO_DEBUG` option. Enabling `explicit-null-checks` also implies
`llvm-disable-implicit-null-checks`, because this option is documented
(e.g. in https://www.mono-project.com/docs/debug+profile/debug/) to
completely disable signal/seh-based null checks.
* Add llvm-disable-implicit-null-checks to the MONO_DEBUG help string.
* Add llvm-disable-implicit-null-checks to mono.1.
* Don't tag null checks in EH regions with `make.implicit`.
This relocates the logic formerly used to guard individual LLVM-level
loads and stores with explicit null checks inside EH regions.
* Use atomic/volatile loads and stores for the terimation flag in thread-suspend-suspended.
LLVM was hoisting the load of and branch against `finished` out of
thread t1's loop, resulting in an infinite spin.
* Use ImplicitNullChecks with LLVM JIT.
* Suppress emission of the .llvm_faultmaps section.
