Live interval utilities

Prev:	clobber-insn
Next:	insn>sync-point ( insn -- sync-point/f )

Vocabulary
compiler.cfg.linear-scan.live-intervals

Class description
Instructions that clobber registers. They receive inputs and produce outputs in spill slots.

Notes
The ##call-gc instruction is not included in the class even though it clobbers registers because it is handled specially.
