* share/txr/stdlib/asm.tl (abscsr): New instruction.
(op-abscsr): New opcode class, derived from op-retsr.
* share/txr/stdlib/compiler.tl: Handle sys:abscond-from via
comp-return-from method.
(compiler comp-return-from): Handle sys:abscond-from by
switching to abscsr opcode instead of ret pseudo-op.

(vm_execute): Dispatch ABSCSR opcode.
* vmop.h: Regenerated.
