[roll] Roll fuchsia [build] Optimize for size rather than speed

This changes the release mode to optimize for size rather than speed
which is aligned with our stated intent for current product priorities.

We also set -mcpu=cortex-a53 for arm64 rather than using the generic
model. This is already set for Zircon but is absent for Fuchsia. We
should be uniformly using -mcpu=cortex-a53 everywhere since it matches
our baseline and avoids unintended changes from compiler updates which
might affect the generic model.

Finally, we also provide a new clang_use_oz option to avoid optionally
changing the optimization level to -Oz rather than -Os which may be
useful in some cases.

Integration

This repository contains Fuchsia's Global Integration manifest files.

Making changes

All changes should be made to the internal version of this repository. Our infrastructure automatically updates this version when the internal one changes.

Currently all changes must be made by a Google employee. Non-Google employees wishing to make a change can ask for assistance via the IRC channel #fuchsia on Freenode.

Obtaining the source

First install Jiri.

Next run:

$ jiri init
$ jiri import minimal https://fuchsia.googlesource.com/integration
$ jiri update

Third party

Third party projects should have their own subdirectory in ./third_party.
