[PATCH 0/7] bitset: use integrer_length in reverse iterations

[Akim Demaille]

This is the continuation of
https://lists.gnu.org/archive/html/bug-gnulib/2020-11/msg00052.html
and
https://lists.gnu.org/archive/html/bug-gnulib/2020-11/msg00075.html
which replaced bit-by-bit forward iterations with uses of ffs, as
suggested by Bruno.  This time, we replace bit-by-bit _backward_
iterations with uses of integrer_length.

The test suite passes with asan and ubsan.  Bison's test suite passes,
but this is irrelevant, since Bison does not depend on reverse
iteration.

I'll push it tomorrow, unless told otherwise.

Cheers!

Akim Demaille (7):
  bitset: tests: check BITSET_FOR_EACH_REVERSE
  bitset: style: sort header
  bitset: style: use consistent names
  bitset: use integrer_length in array implementation
  bitset: use integrer_length in vector implementation
  bitset: use integrer_length in list implementation
  bitset: use integrer_length in table implementation
