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.
