Simon Marchi 1d4b607f0e gdbsupport: add unordered_dense.h 4.4.0
Add a copy of unordered_dense.h from [1].  This file implements an
efficient hash map and hash set with a nice C++ interface (a near
drop-in for std::unordered_map and std::unordered_set).  This is
expected to be used to replace uses of `htab_t`, for improved code
readability and type safety.  Performance-wise, it is preferred to the
std types (std::unordered_map and std::unordered_set) due to it using
open addressing vs closed addressing for the std types.

I chose this particular implementation because it is simple to use, it's
a standalone header and it typically performs well in benchmarks I have
seen (e.g. [2]).  The license being MIT, my understanding is that it's
not a problem to use it and re-distribute it.

Add two additional files, gdbsupport/unordered_map.h and
gdbsupport/unordered_set.h, which make the map and set offered by
gdbsupport/unordered_dense.h available as gdb::unordered_map and
gdb::unordered_set.

		   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.
