linked_regs_too_many_regs checks that collect_linked_regs() ties at most
LINKED_REGS_MAX registers for a single jump. Compare r5 instead of r0,
so that the register the jump compares is itself the member that does
not fit, and check that it comes out of the jump unlinked.
W/o the previous patch env->{false,true}_reg{1,2} bring r5's id back and
insn 7 is logged as "R5=scalar(id=1,...)".
