Simon Marchi 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.
