Fix a number of bugs with inlining calls as function.

Fix a number of bugs with inlining calls as function.

1. Record AST id for CallFunctionStub.

2. Correctly extract cached target from CallFunctionStub inline cache.

3. Fix a bug when inling call as a function in effect or value context:
   Handle abnormal exits correcty.

4. Fix a bug when inlining call as a function in test context: drop function
   correctly from true and false block.

5. Avoid inlining mutually recursive functions by checking the stack of function
   states before inlining. This was not a bug, but is just a more general
   check to avoid recursive inlining.

Thanks a lot for catching and fixing this.  As discussed offline, could we try a
solution based on the pc of the stub call reloc info and avoid having to inspect
every embedded object?

Uploaded new version. The type oracle code is a lot simpler now.
