If call can have type arguments we can't use call->ArgumentAt(0) to
access receiver, instead we need to use call->ArgumentAt(call->FirstArgIndex()).
This lead to a bug in polymorphic inlining of functions with type
arguments - instead of loading class id from the receiver we would be
loading it from the first argument which contains type arguments.
This CL also cleans up other parts of the compiler that used ArgumentAt(0)
when they needed receiver.

This reverts commit cf78da8a48.
Reason for revert: introduces significant performance regression (~30%) on analyzer benchmarks (warm-analysis) without clearly visible hot-spot.

> This reduces small tagged integers on 64 bit platforms from 63 bits to

Previously the graph was constructed in such a way that
:function_type_arguments_var was only initialized when we call the
function with yield points for the first time. Which meant that on
resumption we would the type arguments.
Alternative to this fix would be to capture :function_type_arguments_var
but that does not make sense: yield points only occur inside
non-generic functions at the moment, which means that :function_type_arguments_var
is cheaper then capturing it as it is just a load of a field
from the closure object.

Currently on sim* architectures we use a script snapshot (and not an app
jit snapshot, as we normally do) for the kernel isolate.
-> See utils/application_snapshot.gni:declare_args()
The change in [0] causes a deadlock where we try to compile the kernel
isolate (or rather a script snapshot of it) via the kernel isolate.
This CL fixes all the dartk-sim* builders by allowing us to run the
kernel snapshot from a script snapshot.
