[interpreter] Move function-entry stack check to start of bytecode array
The function-entry stack check should dominate all other
instructions in a function. Prior to this CL it was possible to create
paths not including a stack check due to SwitchOnGeneratorState: the
generator-creation branch had a stack check, while generator-resume
branches did not.
0 : af fb 00 01 SwitchOnGeneratorState r0, [0], [1] { 0: @22 }
4 : 27 fe fa Mov <closure>, r1
7 : 27 02 f9 Mov <this>, r2
10 : 64 0a fa 02 InvokeIntrinsic [_CreateJSGeneratorObject], r1-r2
14 : 26 fb Star r0
16 : a7 StackCheck
17 : b0 fb fb 01 00 SuspendGenerator r0, r0-r0, [0]
22 : b1 fb fb 01 ResumeGenerator r0, r0-r0
[... no stack check here ...]
This CL moves the stack check to the beginning of the bytecode array,
i.e. before SwitchOnGeneratorState.

Reland x3 "[runtime] Remove extension slots from context objects"
Original change's description:
> [runtime] Remove extension slots from context objects
>
> Context objects have an extension slot, which contains further
> additional data that depends on the type of the context.
>
> This CL removes the extension slot from contexts that don't need
> them, hence reducing memory.
>
> The following contexts will still have an extension slot: native,
> module, await, block and with contexts. See objects/contexts.h for
> what the slot is used for.
> The following contexts will not have an extension slot anymore (they
> were not used before): script, catch and builtin contexts.
> Eval and function contexts only have the extension slot if they
> contain a sloppy eval.
>

Revert "Reland "[runtime] Move Context::native_context to the map""
This reverts commit c7c47c68f2c0eb1155cfacab785aba54f61d9218.
Reason for revert: breaks TSAN

Original change's description:
> Reland "[runtime] Move Context::native_context to the map"
>
> This is a reland of f05bae1e0df48aa6a32d958fb4339a85fefb5179
>
> Previously I presumed that the context read from a frame in the profiler was
> a valid context. Turns out that on non-intel we're not guaranteed that the
> frame is properly set up. In the case we looked at, the profiler took a
> sample right before writing the frame marker indicating a builtin frame,
> causing the "context" pointer from that frame to be a bytecode array. Since
> we'll read random garbage on the stack as a possible context pointer, I made
> the code reading the native context from it a little more defensive.
>
> Bug: v8:9860
>
> Original change's description:
> > [runtime] Move Context::native_context to the map
> >
> > Remove the native context slot from contexts by making context maps
> > native-context-specific. Now we require 2 loads to go from a context to the
> > native context, but we have 1 field fewer to store when creating contexts.
