In the MacroAssembler::reserved_stack_check() function:
```
    RuntimeAddress target(StubRoutines::throw_delayed_StackOverflowError_entry());
    relocate(target.rspec(), [&] {
      int32_t offset;
      movptr(t0, target.target(), offset);
      jr(t0, offset);
    });
```
can be simplified to:
```
  la(t0, RuntimeAddress(StubRoutines::throw_delayed_StackOverflowError_entry()));
  jr(t0);
```
