Replace the hand-written gc and print functions with the print and gc

This also requires mapping the label pointers in the byte code back to
the instruction enum. Fortunately this reverse mapping is only needed in
the qmljs case. Normally in the QML engine we persist the byte-code to
disk before linking the compilation unit to the engine (where we map the
enum to goto labels).

GCC6 might dead-store-eliminate out our secret write to Base::mmdata,
because it expects all memory content to be "undefined" before
constructor calls. Clang might take the same approach if the constructor
of Heap::Object is removed.
By making these structs trivial, it also makes them memcpy-able.

The implementation of many (or all) runtime functions consist of first
creating a QV4::Scope, which saves and restores the JS stack pointer.
It also prevents tail-calls because of that restoring behavior. In many
cases it suffices to do that at the entry-point of the runtime.
The return value of a JS function call is now also stored in the scope.
Previously, all return values were stored in a ScopedValue, got loaded
on return, and immediately stored in another ScopedValue in the caller.
This resulted in a lot of stores, where now there is only one store
needed, and no extra ScopedValue for every function.

The as<> casting method was not doing the right thing
in 100% of the cases. It only checked if the object in
question was exactly of the type being asked for. It
however didn't check if the object was derived from the
type.
This commit fixes this by adding a parent chain to the
vtables, that is then being used to check this safely
at runtime.
