This is probably the biggest change to the existing components, as it makes the
summary dropdowns conditional based on the page context. This keeps the old
workflow working, but allows for the new about:profiling page's design. Most
of the diff here is creating the new _renderSection method which consolidates
this logic, and also handles the summary div structure.

The new about:profiling page creates some more complexity around what
the page context is. It is simpler to handle the different cases with
a union, rather than booleans.

SABs become foreground-finalizable so that we can access the runtime
during finalization.  Then a simple counter on the runtime will track
live SABs for the runtime, and the predicate on the context can get
its information from the runtime.

Fallout: SABs are now enabled on the globals used for jsapi-tests.

Some OpenGL ES implementations do not like how we overflow a signed

Historically there were kludges in how we chose to snap layers and
transforms, nominally for performance reasons (see bug 602200 comment
36). WebRender appears to render what was considered at the time the
ideal outcome, which also makes the most sense as a content author.
Given we are otherwise lacking a reason to continue with the old
behaviour, this patch adds a new test case to confirm WebRender snaps in
the ideal fashion, and non-WebRender does not.

Bug 1601219 - Use the right PageStyleFront instance when querying computed styles from the color picker; r=rcaliman

It looks like we left out some places in the inspector when we made it fission-compatible.
The color-picker, in particular, needs access to the selected node's computed style for its
color contrast logic.
We used to access this on the top-level target PageStyleFront. We just need to change this so
it uses the one contextual to the selected node.

Mechanical rename/merge for the most part.

When restarting a loop in IonBuilder, we skip the JSOP_LOOPHEAD so we
now re-add the interrupt check (this used to be done by JSOP_LOOPENTRY)
explicitly by calling emitLoopHeadInstructions.

This is necessary for the next patch: it will merge JSOP_LOOPHEAD
and JSOP_LOOPENTRY but that means there can be multiple callVMs for
that op and this confuses DebugModeOSR (interrupts can trigger debugger
recompilation).

All loops now have the same structure. A later patch in the stack
will remove this class.

Differential Revision: https://phabricator.services.mozilla.com/D55626

--HG--
extra : moz-landing-system : lando

This changes all loops to have the following bytecode structure:
```
JSOP_LOOPHEAD
JSOP_LOOPENTRY
...condition/body...
JSOP_GOTO/JSOP_IFEQ/JSOP_IFNE
```

This simplifies IonBuilder a lot because it can use the do-while code path
for all loops. For-in loops are also a bit simpler now because they no longer
need to have the next enumerated value on the stack across the backedge.

Later patches in the stack wil fold JSOP_LOOPENTRY into JSOP_LOOPHEAD,
simplify the source notes more and remove more code from IonBuilder.

I verified stepping/breakpoints for the different loop types works in the
debugger the same way as before this patch.
