Heap::InNewSpace only needs to access the heap for a DCHECK and the part

case getting it via pointer magic is fine.

This CL completes the implementation of DataView prototype methods
in TurboFan, by implementing the Uint8, Int8, Uint16, Int16,
Uint32, Int32, Float32 and Float64 setters.
DataView performance is now ahead of the equivalent TypedArray wrapper,
and is now expected to at least match TypedArray performance in
the general case as well.
This CL also adds a test file in the compiler directory, to make
sure that the setters actually behave correctly.

Add new types for function data for SharedFunctionInfo, for uncompiled
functions. UncompiledData holds start/end positions, allowing us to
remove these fields from SFI. Uncompiled functions with pre-parsed
scope data now hold an UncompiledDataWithScope that has a pointer to
PreParsedScopeData -- this allows us to also remove the start/end pos
from PreParsedScopeData.

This extends the current Promise Rejection Hook with two new events
kPromiseRejectAfterResolved
kPromiseResolveAfterResolved
which are used to detect (and signal) misuse of the Promise constructor.
Specifically the common bug like
new Promise((res, rej) => {
res(1);
throw new Error("something")
});
where the error is silently swallowed by the Promise constructor without
the user ever noticing can be caught via this hook.

Instead of creating a separate code object per exported function, we
can share the code per signature, and load the function index from the
{WasmExportedFunction} object which is being passed as an argument
anyway.
This greatly reduces instantiation time for modules with a lot of
exports.
As a next step, we could even share the code across instances, or (with
more work) across isolates.
