Tom Tromey c7b15a66dc Fix Rust enum test failures
Pedro pointed out that some Rust tests were failing after the recent
enum change.  I was able to reproduce this even with the most current
Rust compiler -- no test was failing, but rather the gdb internal
error was causing an "untested" result, which I didn't notice.

The internal error is caused by a bad assertion in
alloc_discriminant_info.  This happened because, in an earlier version
of the patch, the discriminant could only appear at index 0.  However,
it can now appear anywhere.  This patch fixes the assertion in the
obvious way, and adds a second assertion to ensure that the
discriminant is also correct.

Fixing this revealed a real failure, which was caused by using the
wrong base name when computing the name of a univariant enum's sole
member.  This is also fixed here.

Tested by running the gdb.rust tests with rustc 1.23 and
double-checking the summary:

    # of expected passes		276

Note that if you try this yourself, it is still possible to get an
"untested" result from traits.exp if your Rust compiler is old enough.

	* dwarf2read.c (alloc_discriminant_info): Fix default_index
	assertion.  Add assertion for discriminant_index.
	(quirk_rust_enum): Use correct base type name in univariant case.

		   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.
