This minor optimization is easily implemented: If there are no tests to verify, call fatal(0).
However, I encountered a minor obstacle: If the task exits before creating the upload directory,
the task fails, regardless of exit value; the remaining changes overcome this by creating the
upload directory earlier.

When we first enabled ThinLTO on our builds, we got great performance gains, but also large size increases due to aggressive inlining. There is an LLVM option called -import-instr-limit that limits the size of functions that may be imported (the threshold is subject to modification by PGO). Chromium found a good balance between speed and performance by using a value of 10. In initial testing, on Windows and Linux that value can save us many megabytes from libxul without noticeable speed regressions. For Mac, which doesn't yet have PGO, we have to use a higher limit to avoid over-restricting the optimizer which caused slowdowns on my try pushes.

Instead of checking for canonical function using scope chain, we can
directly use the functionOrGlobal field. By moving this to the
BaseScript class we can also simplify the debugger acccess.

To avoid calling JSScript::function() from finalizer, we need to read the

To allow InitScriptCoverage to be more flexible, we need to delay the call
until the JSScript is actually initialized. This moves the calls from
JSScript constructor until the JSScript is actually initialized. This is
similar to the debugger onNewScript call, but more cleanup would be needed to
unify these.

Set this flag for scripts that are for functions. This is equivalent to
checking the kind of the bodyScope() but is safe to call in GC contexts such
as finalization.
Also use an isFunction() accessor instead of checking if JSScript::function()
is nullptr throughout the codebase. Similarly, cleanup similar uses of
JSScript::module().

nsPrintData::mBrandName never changes over the lifetime of a Firefox instance.
It is wasteful to have nsPrintData obtain and store it, since we can replace
an nsPrintJob's nsPrintData object multiple times over the lifetime of the
nsPrintJob and nsPrintJob is the only consumer.

* Adds a new moz-http2-child.js file which gets spawned into a new process. When calling NodeServer.execute, the code gets passed to the existing moz-http2.js process which then sends it to be evaluated in the child process. Any crash in the child should not be able to kill the main node process.
* Moves the proxy creation code into test_http2-proxy.js
* Adds the new NodeServer.fork() and NodeServer.kill() static methods to spawn a new server
* Makes it easier to isolate a test's behaviour from another's. It also opens the way to moving some of the logic to individual unit tests, like we do for the proxy creation code, rather than keeping it all in moz-http2.js

The previous code tried to do it, but it did it wrongly, as the overflow clip
comes from the parent, not the child.
Thus when we change a style that influences it, we weren't invalidating the
SIMPLE_DISPLAY_LIST bit, and such.
Make the reftest that caught this fail more reliable.

This patch fixes some issues with binaries not being executable after being extracted. It also fixes the ImageMagick expected extraction path to the correct location. To prevent that from occuring again, a check is done after extraction to be sure that the extraction completed successfully.

During the visibility pass, picture caches register themselves as
occluders, if they have a valid opaque region.
During the primitive preparation pass, each tile queries if it is
occluded. If so, it skips rasterization and compositing of itself
for this frame. In this way, tiles that are always occluded never
end up allocating GPU memory for a surface.
Also add support during primitive dependency generation for opaque
images to be considered as part of the opaque backdrop region.

Instead, this patch introduces a new `ObjLiteral` mini-bytecode format
that is used to carry object-literal information from parse time to a
later time at which GC objects are safe to allocate. The mini-bytecode simply
specifies a list of fields and constant field values.
The original intent of this patch (realized in previous versions of it)
was to make this an opcode, and completely replace object creation
sequences (NEWINIT, INITPROP, INITPROP, ...) with one OBJLITERAL opcode.
However, there are quite a few performance regressions that occur when
replacing the finely-tuned set of optimizations around this with a new
mechanism.
As a result, this patch only defers allocation of the objects until the
very end of parse. Each object literal adds an ObjLiteralCreationData
instance to the GC-things list, and when the GC-things list is processed
to perform deferred allocations, the described objects will be created.
