formats. This also encapsulates some of the spectre mitigations.

Now that all the bad type-punning is gone, JS::Value has a single
asBits_ field and we should use a class aggregate type instead.

Use well-defined conversions on the asBits_ instead. This removes union
arms entirely. They are slighly useful for debugging, but we don't have
that on our 64-bit platforms and the gdb helpers can already help us
out.

Use well-defined conversions on the asBits_ instead. The remaining union
arms were not even helpful for debuggers so we remove entirely.

BrowsingContext.findWithName is required to do access checks based on the
requestor, which can only be done in the process which owns it. This change
also alters the behavior of the existing CanAccess origin checks, which
typically treat any item as same-origin, but only when the docshells are
actually same process.
Removing the exemption fixes the behavior discrepancy between Fission and
non-Fission runs, but also requires that the test be updated to expect proper
access checks. Which is the situation we really want to test, anyway.

In some situations, entries may in fact take more than half the buffer size
(e.g., when duplicating a stack into a small temporary buffer).
So we now allow blocks to take the full buffer size -- but not more, as they
would start overwriting themselves!

* wpt runs chrome priv for a subset of tests (mostly things testing toolkit chrome stuff), but it's still in the content process
* we only ever hit this case if the test is explicitly loaded as chrome. originally added for a couple osx tests at https://bugzilla.mozilla.org/show_bug.cgi?id=1465457. then expanded for all xul tests at https://bugzilla.mozilla.org/show_bug.cgi?id=1557371
* so what we used to do here is run xul/xbl in the content process (not chrome priv)
* the change here is that with our chrome Custom Elements we need to run with chrome priv for https://searchfox.org/mozilla-central/rev/4218cb868d8deed13e902718ba2595d85e12b86b/toolkit/components/processsingleton/CustomElementsListener.jsm#16 to load the elements
* so we made it explicit. the alternative at the time was to change wpt harness to load these tests in parent process, but it was too complex for what we needed (discussed with dbaron)
* this parentprocess check was meant kind of as an optimization so that we wouldn't have to check priv on random pages. but (a) that's short circuited anyway by the xul elem check and (b) this is only called when attachShadow is called on a non-html element so not in any kind of hot path

Increase max-run-time for linux and windows ccov browser-chrome tasks to avoid
frequent task timeouts. (linux platform name was incorrect in existing configuration).
I would prefer to see shorter max-run-time but there may be no alternative for
these tasks.

Before this change, browserActions and pageActions did not trigger
onClick events when middle-clicked, and no information on the button or
any modifiers were passed in the onClick event. With this change, middle
clicking triggers an event, and a clickData object is passed in the
onClick event, with the button and a list of modifiers.

It appears possible for data eviction to take place despite the manager not
currently having any buffered ranges. This shouldn't happen, but if it can if
the buffers have become full with 0 duration data. This patch attempts to
mitigate that case by removing all coded frames. This prevents a bad access on
the buffered ranges and should clear up space in the buffers to append more
data.
