Implement new popcntr instruction.

* check/popcnt.tst, check/popcnt.ok: New test files for the new popcntr instruction. * check/Makefile.am, check/lightning.c, include/lightning.h.in, lib/jit_names.c: lib/lightning.c, doc/body.texi: Update for popcntr. * lib/jit_aarch64-fpu.c, lib/jit_aarch64.c: Implement optimized popcntr using the fpu. * lib/jit_alpha-cpu.c, lib/jit_alpha.c: Implement optimized popcntr using the ctpop instruction. * lib/jit_arm-vfp.c, lib/jit_arm-cpu.c, lib/jit_arm.c: Implement untested optimized popcntr using vfp >= 4, otherwise use a software fallback. * lib/jit_ia64-cpu.c, lib/jit_jia64.c: Implement optimized popcntr using the popcnt instruction. * lib/jit_ppc-cpu.c, lib/jit_ppc.c: Implement optimized popcntr using the popcntb, plus mullr and rshi_u instruction. * lib/jit_x86-cpu.c, lib/jit_x86.c: Implement optimized popcntr instruction using the popcnt instruction if available, otherwise use an optimized fallback. * lib/jit_fallback.c: Implement simple fallback popcnt. * lib/jit_hppa.c, lib/jit_loongarch.c, lib/jit_mips.c, lib/jit_riscv.c, lib/jit_s390.c, lib/jit_sparc.c: Use fallback popcnt.
