[roll] Roll fuchsia [debugger] Add debug_addr context to expressions.

Implementing DW_OP_addrx requires being able to read the .debug_addr
section and the DW_AT_addr_base from the compile unit. This patch adds
that context, but does not implement the code to actually read the
.debug_addr section or implement the addrx operation. That will be added
in a followup.

To give the proper context, the "source symbol" is needed for DWARF
expressions. A new DwarfExpr object is added and used in places where
before we used std::vector<uint8_t>. This required many trivial updates
across the codebase.

Reading the DW_AT_addr_base from the compilation unit is also added.

There should be no behavior change.

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.
