[roll] Roll fuchsia [kernel][arm64] Use <lib/arch/asm.h> conventions in exceptions.S

This modernizes kernel/arm64/exceptions.S to use the macros from
<lib/arch/asm.h> and more modern assembly conventions.  It also
reorganizes the local macros with more thorough comments and
adjustments to the CFI.

Disassembly (objdump -rd) for the built exceptions.S shows no
change and CFI dumps (readelf -W --debug-dump=frames) show only
the intended changes.

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.
