Tom Tromey fcfcc37696 Fix qualified name lookup for Rust
In https://github.com/rust-lang/rust/pull/46457, "m4b" pointed out
that the Rust support in gdb doesn't properly handle the lookup of
qualified names.

In particular, as shown in the test case in this patch, something like
"::NAME" should be found in the global scope, but is not.

This turns out to happen because rust_lookup_symbol_nonlocal does not
search the global scope unless the name in question is unqualified.
However, lookup_symbol_aux does not search the global scope, and
appears to search the static scope only as a fallback (I wonder if
this is needed?).

This patch fixes the problem by changing rust_lookup_symbol_nonlocal
to search the static and global blocks in more cases.

Regression tested against various versions of the rust compiler on
Fedora 26 x86-64.  (Note that there are unrelated failures with newer
versions of rustc; I will be addressing those separately.)

2018-01-19  Tom Tromey  <tom@tromey.com>

	* rust-lang.c (rust_lookup_symbol_nonlocal): Look up qualified
	symbols in the static and global blocks.

2018-01-19  Tom Tromey  <tom@tromey.com>

	* gdb.rust/modules.rs (TWENTY_THREE): New global.
	* gdb.rust/modules.exp: Add ::-qualified lookup test.

		   README for GNU development tools

This directory contains various GNU compilers, assemblers, linkers, 
debuggers, etc., plus their support routines, definitions, and documentation.

If you are receiving this as part of a GDB release, see the file gdb/README.
If with a binutils release, see binutils/README;  if with a libg++ release,
see libg++/README, etc.  That'll give you info about this
package -- supported targets, how to use it, how to report bugs, etc.

It is now possible to automatically configure and build a variety of
tools with one command.  To build all of the tools contained herein,
run the ``configure'' script here, e.g.:

	./configure 
	make

To install them (by default in /usr/local/bin, /usr/local/lib, etc),
then do:
	make install

(If the configure script can't determine your type of computer, give it
the name as an argument, for instance ``./configure sun4''.  You can
use the script ``config.sub'' to test whether a name is recognized; if
it is, config.sub translates it to a triplet specifying CPU, vendor,
and OS.)

If you have more than one compiler on your system, it is often best to
explicitly set CC in the environment before running configure, and to
also set CC when running make.  For example (assuming sh/bash/ksh):

	CC=gcc ./configure
	make

A similar example using csh:

	setenv CC gcc
	./configure
	make

Much of the code and documentation enclosed is copyright by
the Free Software Foundation, Inc.  See the file COPYING or
COPYING.LIB in the various directories, for a description of the
GNU General Public License terms under which you can copy the files.

REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info
on where and how to report problems.
