Tom Tromey 1dffa580e7 Avoid undefined behavior in expression dumping
-fsanitize=undefined pointed out undefined behavior in
dump_raw_expression like:

    runtime error: load of value 2887952, which is not a valid value for type 'exp_opcode'

dump_raw_expression will try to print the opcode for each element of
the expression, even when it is not valid.  To allow this, but have it
avoid undefined behavior, this patch sets the underlying type of enum
exp_opcode, and arranges for op_name to handle invalid opcodes more
nicely.

Before this patch, debug-expr.exp shows:

Dump of expression @ 0x60f000007750, before conversion to prefix form:
	Language c, 8 elements, 16 bytes each.
	Index                Opcode         Hex Value  String Value
	    0               OP_TYPE  89  Y...............
   <unknown 3851920>  107820862850704  ..:..b..........
	    2               OP_TYPE  89  Y...............

	    6          OP_VAR_VALUE  40  (...............
	    7      UNOP_MEMVAL_TYPE  57  9...............

Afterward, the output is:

Dump of expression @ 0x4820f90, before conversion to prefix form:
	Language c, 8 elements, 16 bytes each.

		   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.
