InternalProperty in mirror-debugger.js and ARM experimental assert
This change is a partially commented implementation of InternalProperty support that happens to crash in Release ARM configuration. A runtime-time assert in lithium-codegen-arm.cc presumably marks the problem that leads to the crash.
I run d8 with following command-line:
--stress-opt --expose-debug-as debug test/mjsunit/mjsunit.js test/mjsunit/mirror-object.js --test --stress-runs=5
It happens on the 5th iteration of the stress test.
