YJIT: Fix --yjit-dump-insns by removing {cpush,cpop}_all() in printers

cpush_all() and cpop_all() in theory enabled these `print_*` utilities
to work in more spots, but with automatically spilling in asm.ccall(),
the benefits are now limited. They also have a bug at the moment. Stop
using them to dodge the bug.
