This already had code to check both black and gray bit since that's needed to
work out whether something is marked gray. We can do the black check first and
bail early which skips calling into the JS engine for black things.

This tests that JS holders get marked gray by GC and updated when moved by
compacting GC. The latter would have caught the problem reported in bug

Bug 1734087 part 1 - Don't capture a stack trace for every throw-statement in non-debuggee realms. r=sfink

Stack walking is slow. Match Chrome by only capturing an exception stack if the
realm is a debuggee. Additionally, we also capture stacks for chrome code, and for
the first 50 throws per realm to not penalize debugging of JS code that doesn't
throw a ton of exceptions.

Note that this is unrelated to Error.stack. That's handled separately and is observable
from JS. The stacks here are used by the debugger for uncaught exceptions that are
not Error objects.

GC reasons clobber each-other as follows:

USER_INACTIVE > FULL_GC_TIMER > all others.

To ensure that if multiple timers fire we still do the strongest GC
requested.

Gecko taskgraph is now an official consumer of standalone taskgraph.

I chose 'util/yaml.py' since both copies were identical. I've also synced the
test for them, so no coverage is being lost.

Bug 1734540: For a11y browser tests, allow snippets when passing chrome: true to load as a chrome document in the parent process. r=eeejay

Normally, we use data: URLs to load snippets as tab documents.
However, there is no way we can make this load in the parent process.
Using a chrome:// URL will allow us to load a file in the parent process.
For OOP iframes, we use document-builder.sjs to yield a document with supplied markup, but sjs doesn't work for chrome:// (since sjs is handled by our test web server).
Instead, for chrome://, we use an HTML file with an embedded script which replaces the content of the document with the supplied markup.

the deprecated LineBreaker::DeprecatedNext() (added in bug 1733872).

blockquote citation still works. The testcase's behavior is not changed.
