ART: Introduce stackmap with no DexRegInfo.
Some of safepoints don't need to have DexRegisterMap info;
this will decrease the stackmap size.
.oat file size reduction:
- boot.oat: -233 kb (-5.4%)
- boot-framework.oat: -704 kb (-4.9%)
Test: 461-get-reference-vreg, 466-get-live-vreg.
Test: 543-env-long-ref, 616-cha*.
Test: test-art-target, +gc-stress.
