Remove the `CanTriggerGC` side-effects on a few instructions.

The side-effect was specified for these instructions as they call
runtime. We now have a list of entrypoints that we know cannot trigger
GC. We can avoid requiring the side-effect for those.

Test: Run ART test suite on Nexus 5X and host.
