This enables {FLAG_debug_code} by default in debug builds. The advantage
is that generated code contained within the snapshot will contain such
debug code. Before we would only get coverage for these pieces with the
no-snapshot builds, which have a meager coverage. One can still pass the
inverse --no-debug-code flag to ensure generated code remains readable
within debug builds as well.

To make better inlining decisions, it's good to have call counts for poly/mega-morphic cases. This CL makes it work for calls, and another will follow to better unify the code between constructor calls and normal calls (and thence, to record megamorphic call counts there as well).

In the process also inline the stub into the appropriate interpreter bytecode
handler and make sure that the context register is preserved in hand-written
assembly code that calls the stub and expects the context register to be
preserved.

Collect type feedback in the call bytecode handler. The current
implementation only collects feedback for JS function objects. The other
objects and Array functions do not collect any feedback. They will be
marked Megamorphic.
