Correctly perform read-barriers on cross-thread reg access
For debug workloads we will sometimes read stack registers on other
threads. This generally only happens when the target thread is
suspended due to a running GC and the debugger thread tries to access
stack registers from a compiled method. This could lead to a missed
read-barrier and a From-Space reference being returned. To fix this we
manually perform a read-barrier after pulling the reference out of the
compiled stack.
Test: ./test.py --host
Test: ./art/tools/run-libjdwp-tests.sh --mode=host
Test: ./test.py --host --all-compiler --all-gc -t 1966
