Revert "Revert "Basic obsolete methods support""

This reverts commit b81a9840b44480bfeacd74b8d9f51e06f295411d.

There were 2 issues with the original CL's test 916-obsolete-jit that
caused it to sporadically fail.

First, when checking if we had jitted the function under test in
916-obsolete-jit we failed to check to see if the function 'doCall',
which is used to work-around bugs in our deoptimization & compilation
systems, had also been jitted.

In the case where the 'sayHi' function had been jitted but the
'doCall' function had not we would (correctly) fail to redefine the
'Transform' class since we would not be able to deoptimize the 'sayHi'
function since it is under a quick_to_interpreter_bridge (runtime)
frame.

Secondly, the function Main.isInterpretedFunction was incorrect and
would always return false, regardless of the actual state of the
function. This would cause the test to fail as the
quick_to_interpreter_bridge frame prevented deoptimization of the
obsoleted function. Usually the warm-up period was enough to make sure
the methods were jitted anyway but this was not guaranteed.

Both of these problems become more likely to occur on systems with
more cpu contention such as the buildbots.

Test: stress --cpu 60 &; while ./test/run-test --host --jit 916; do ; done
