Eli Zaretskii b3885679dd Fix handling DLL loads at run time
This patch makes handling a DLL load at run time (using LoadLibrary)
much more reliable when its file name cannot be obtained using the
lpImageName pointer provided by the DLL load debug event.  The
solution is to enumerate all the DLLs loaded by the inferior, looking
for the DLL that's loaded at base address provided by the lpBaseOfDll
pointer of the debug event.  Correctly resolving the DLL file name is
important, because without that GDB doesn't record the DLL in the list
of solibs, and then later is unable to show functions in that DLL in
the backtraces, which produces corrupted and truncated backtraces.
See this thread for the problems that causes:

gdb/ChangeLog:

2021-04-10  Eli Zaretskii  <eliz@gnu.org>

	* windows-nat.c (windows_nat::handle_load_dll): Call
	windows_add_dll if get_image_name failed to glean the name of the
	DLL by using the lpImageName pointer.
	(windows_add_all_dlls): Now a thin wrapper around windows_add_dll.
	(windows_add_dll): Now does what windows_add_all_dlls did before,
	but also accepts an argument LOAD_ADDR, which, if non-NULL,
	specifies the address where the DLL was loaded into the inferior,
	and looks for the single DLL loaded at that address.

		   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.
