Android doesn't have swap space so if the heap goes over the physical memory
size the system will just kill us. Applying the Heap::kPointerMultipler
to heap size could cause the max heap size to be larger than physical memory.
Instead use the defaults which are based on actual physical memory configured
by Api::ConfigureDefaults().

TryInline needed position only for the case when we track positions.
We can drop the position argument and use the current position from GraphBuilder.
The only problem that it doesn't match with the inline point.
The reason of that was the fact that builder had moved the position forward by
visiting arguments expressions.

I fixed this by restoring the current positon in HOptimizedGraphBuilderWithPositions::Visit*

Contribution of PowerPC port (continuation of 422063005, 817143002,
866843003, and 901083004. This patch updates the ppc directories
to make them current with changes in common code, removes the
optimization to use the ool constant pool, and excludes tests that
don't pass under the ppc simulator given a 240s timeout.

Subsequent patches will cover:
   - remaining optimizations for PPC
   - remaining AIX changes not resolved by 4.8 compiler (4.8 is only recently available for AIX)
   - incremental updates required to ppc directories due to platform specific changes made
    in google repos while we complete the above steps.

On Intel targets, it is cheaper to load the context from the frame
instead of loading the context as a constant (which usually involves a
PropertyCell because the context is in new space when we compile the
function).

The auto-push script is only used in an automated fashion
on bots. It doesn't need to check for a clean git
environment as it has a special workdir checkout.

If the release creation fails for whatever reason (e.g.
a master restart happens in the middle), the workdir
checkout might be left dirty. Any new attempt of the auto
pusher then bails out.

After this change it will call the create_release script
in any case which tidies up the workspace on startup.

InstallBuiltinFunctionIds stood out when looking at code that grew
strangely when compiled with default optimizations.

This change from repeated code to a loop saves 6-7 KB of machine code.
I suspect it's faster but I also suspect it's fast enough either way so
that is not really a factor. Machine code reduction seen below.

Code formatted with git cl format.
