vm: missed cases of signal check in backwards branch
Only the JMP instruction is checking for a backwards branch
and calling sig_check_fast() so that a loop can be interrupted
by Ctrl-C. The compiler can optimize that so that a backwards
jump is performed by an instruction in the IF family.
* vm.c (vm_if, vm_ifq, vm_ifql): Check for a backwards
branch and call sig_check_fast. Also, eliminate the redundant
call to vm_insn_bigop, which is just a masking macro.
The ip variable is already the result of vm_insn_bigop.
