Off-heap-safety slightly differs from isolate-independence in that it
allows external references and checks instruction-size constraints.
This adds the new predicate as well as a cctest verifying it. New
DCHECKs are introduced to document assumptions and upcoming work.
Note that this breaks the --stress-off-heap-code flag. Fixes will
follow in upcoming CLs.

When calling a function through a function table, check whether the
instance of the called function differs from the current instance, and
in that case call the other function via a c-wasm-entry instead of
interpreting it.
The c-wasm-entry needs to pass the wasm context, so this CL changes
this to receive the wasm context as parameter instead of embedding the
context of the calling instance.

This is preparatory cleanup work for eventually tracking the functions
(rather than concrete closures) in the CALL_IC, also for builtins like
the default PromiseCapability [[Resolve]] and [[Reject]] functions. It
adds a new FeedbackCell type, which is used by JSFunctions consistently
now to reference the feedback vector (or undefined if not the function
is not compiled yet or is a native/asm.js function).
This also changes the calling convention for FastNewClosure builtin and
the JSCreateClosure operator in TurboFan to carry the FeedbackCell here
instead of the parent FeedbackVector and the slot index. In addition we
eliminate the now unused %InterpreterNewClosure runtime function.

IterableToListCanBeElided checked that the input was always a HeapObject
but this is not true when an iterator symbol is defined on the Number
prototype, meaning Smi and HeapNumber can also be passed in.
Added a regression test for the crash and some correctness tests for
smi and double input to TA.from.
Also factored out the tests in typedarray-from.js that modify global
state e.g. protector cells, so that one iteration of the top level
loop does not interfere with the next.

Private fields should not return undefined on access miss, but instead
should throw a TypeError.
This patch uses a bit on v8::Symbol to mark if this symbol is a
private field or not.
This patch also changes the LookupIterator code path that deals with
LookupIterator::State::DATA to deal with JSReceiver instead of
JSObject.
Note: the error message doesn't output the field name, but that's a
