This patch uses the Windows.System.Profile.WindowsIntegrityPolicy class to determine whether or not Windows is in S mode. This class is only available beginning with SDK 17763 (newer than what we use right now), so we need to fetch it at runtime with some magic.
This is a completely no-op for Windows versions older than 1810, where the WindowsIntegrityPolicy class is not available.

These logs have been added to help with the investigation of shutdown issues. But it turned out to not be that helpful. Lets get it removed from wdspec jobs to lesser clutter the logs.

This is a pointer-sized value, so there's no need to pass it by
value. All of the SpiderMonkey places that pass GCCellPtr are doing
it by value, so this is aligning with that.
In addition, I removed a NoteJSChild() overload that is no longer
used.

For running in FIPS mode, NSS needs to check /proc/sys/crypto/fips_enabled, to be able to tell whether FIPS is enabled or not.
FIPS also mandates using /dev/random instead of /dev/urandom.

After the preparations from the preceding patches, we can now simply enable
transpiling `SpreadNew` and `SpreadSuperCall`.

Adds `MConstructArray::needsThisCheck` so we can pass this flag to `MakeCall()`
in `ArrayMemoryView::visitConstructArray()`. This is needed because the next
patch will change `MConstructArray` to store a single caller in
`MConstructArray::target_` and we have assertions in place which disallow to
emit a `this`-check when we know it's unnecessary (because the target function
is known).

No change in behaviour, only changes `build_SpreadNew()` to call `makeSpreadCall()`
in preparation for the next patches in this stack.
Additionally moves the `MCreateThis::New` call from `WarpBuilder::buildCallOp()`
into a new method `WarpBuilder::buildCreateThis()`.

Adds a copy of `ApplyArgs` to handle constructor calls. This new instruction is
then used to scalar replace rest arrays in `new` and `super` spread calls.
With this patch applied, we can scalar replace rest parameters in derived class
constructors:
```
class Derived extends Base {
constructor(...args) {
super(...args);
}
}
```

This follows the existing scalar replacement support for `arguments`. When the
rest array isn't modified, we can read the rest array elements from the frame.
And the rest array length can be computed through `max(numActuals - numFormals, 0)`.
There isn't yet support for scalar replacing rest arrays in `MApplyArray` when
additional formals are present, because `MApplyArgs` doesn't yet cover this case.
Differential Revision: https://phabricator.services.mozilla.com/D130484
Add recover support for `MRest`. When rest arguments are present, the `arguments`
object isn't mapped, so the rest array can be directly recovered from the frame.

Otherwise the origin of the rect might not be correctly converted.
We have a supposed test for something like this:
layout/reftests/forms/input/number/spinner-overflow-vertical.html
But in practice it doesn't work, because I removed the "overflowing
descendants inflate outlines" behavior (bug 1739894), and even with that
pref it doesn't seem to cut it... So repurpose that test to test both.

Annotating each test individually lets us avoid introducing new failing tests
while we go through the backlog of failing tests.

Introduce a command line jit option that allows codegen functions that
emit debug code to know when to emit less of it. I'm currently using
this only in one place but it would be useful to use it more often, to
simplify whitebox testing of codegen.
Also give a better (and more typical) name to a function that
emits debug code.

Current code is not explicit about device recreation before session re-creation. It is actually done by nsWindow::OnPaint() before OnInProcessDeviceReset() call. But it is not explicit.
gfxWindowsPlatform::HandleDeviceReset() does d3d device re-creation if it is necessary.
