count-leading-zeros: Assume that the compiler supports 'long long'.
* lib/count-leading-zeros.h (count_leading_zeros_ll): Define
unconditionally.
* m4/count-leading-zeros.m4: Remove file.
* modules/count-leading-zeros (Files): Remove it.
(configure.ac): Don't invoke gl_COUNT_LEADING_ZEROS.
* tests/test-count-leading-zeros.c (main): Test count_leading_zeros_ll
unconditionally.
