Rewrite null checks in read barrier introspection thunks.
Rely on the implicit null check in the fast path.
Test: Manual; run-test --gdb 160, break in the introspection
entrypoint, find the mf.testField0000 read barrier
code in the caller (this one has a stack map for null
check, most other reads do not need one), break there,
step into the thunk, overwrite the base register with
0 and observe the NPE being thrown. Repeat with --64.
Test: Pixel 2 XL boots.
Test: testrunner.py --target --optimizing
