5df4cba632 gdb: update gnulib import 
This is mostly to get this commit from gnulib:

    e22cd2677a4b7beacbf30b93bb0559f7b89f96ce
    Add ‘extern "C"’ to count-one-bits.h etc.

... which fixes this compilation problem I observed with clang++:

      CXXLD  gdb
    arch/arm-get-next-pcs.o:arm-get-next-pcs.c:function thumb_get_next_pcs_raw(arm_get_next_pcs*): error: undefined reference to 'count_one_bits(unsigned int)'
    <more such undefined references>

I built-tested on GNU/Linux x86-64 (gcc-9 and clang-9) as well as with the
x86_64-w64-mingw32-gcc cross-compiler.

gnulib/ChangeLog:

	* update-gnulib.sh (GNULIB_COMMIT_SHA1): Bump to
	e22cd2677a4b7beacbf30b93bb0559f7b89f96ce.
	* Makefile.in, config.in, configure, import/*: Re-generate.

5f661e0397 gnulib: import count-one-bits module and use it 
For a fix I intend to submit, I would need a function that counts the
number of set bits in a word.  There is  __builtin_popcount that is
supported by gcc and clang, but there is also a gnulib module that wraps
that and provides a fallback for other compilers, so I think it would be
good to use it.

I also noticed that there is a bitcount function in arch/arm.c, so I
thought that as a first step I would replace that one with the gnulib
count-one-bits module.  This is what this patch does.

The gnulib module provides multiple functions, with various parameter
length (unsigned int, unsigned long int, unsigned long long int), I
chose the one that made sense for each call site based on the argument
type.

gnulib/ChangeLog:

	* update-gnulib.sh (IMPORTED_GNULIB_MODULES): Import
	count-one-bits module.
	* configure: Re-generate.
	* aclocal.m4: Re-generate.
	* Makefile.in: Re-generate.
	* import/count-one-bits.c: New file.
	* import/count-one-bits.h: New file.
	* import/Makefile.am: Re-generate.
	* import/Makefile.in: Re-generate.
	* import/m4/gnulib-cache.m4: Re-generate.
	* import/m4/gnulib-comp.m4: Re-generate.
	* import/m4/count-one-bits.m4: New file.

gdb/ChangeLog:

	* arm-tdep.c: Include count-one-bits.h.
	(cleanup_block_store_pc): Use count_one_bits.
	(cleanup_block_load_pc): Use count_one_bits.
	(arm_copy_block_xfer): Use count_one_bits.
	(thumb2_copy_block_xfer): Use count_one_bits.
	(thumb_copy_pop_pc_16bit): Use count_one_bits.
	* arch/arm-get-next-pcs.c: Include count-one-bits.h.
	(thumb_get_next_pcs_raw): Use count_one_bits.
	(arm_get_next_pcs_raw): Use count_one_bits_l.
	* arch/arm.c (bitcount): Remove.
	* arch/arm.h (bitcount): Remove.

c0c3707ff4 Update Gnulib to the latest git version 
This patch allows us to remove a workaround in common-defs.h due to
the gnulib fix in:
https://lists.gnu.org/archive/html/bug-gnulib/2019-11/msg00024.html

All of GDB's local Gnulib patches were already fixed upstream per their
descriptions, so this patch removes them all.

The problem listed here:
https://sourceware.org/ml/gdb-patches/2019-08/msg00553.html
was probably partially fixed by moving gnulib to the toplevel;
for the remainder, I am setting MAKEOVERRIDES to empty in
gnulib/Makefile.am.  See also the comment there (it fixes an issue
with compilers that don't use C99/C11 by default such as GCC 4.8.5,
the default on Centos 7).

	* gdbsupport/common-defs.h: Remove workaround for a gnulib bug

e176f82170 Add no-dist to gnulib configure 
This adds the no-dist option to the gnulib configure script.  gdb
doesn't use "make dist", so there's no need for this.  Adding this
option makes the Makefiles less verbose.

73cc72729a Move gnulib to top level 
This patch moves the gdb/gnulib subdirectory to the top level.

It adjusts the top-level build system to build gnulib when necessary,
and changes gdb to use this.  However, gdbserver still builds its own
copy of gnulib, just from the new source location.

A small hack was needed to ensure that gnulib is only built when gdb
is enabled.  The Makefile only provides an ordering -- the directory
must be mentioned in configdirs to actually be compiled at all.

Most of the patch is just a "git mv" of gnulib, though a few minor
path adjustments were needed in some files there.

Tested by the buildbot.
