JSFunction is one of a few JSObject classes that uses its own custom data layout:
https://searchfox.org/mozilla-central/source/js/src/vm/JSFunction.h#43-131
This adds complexity to object allocation and in the GC (and probably other places too). It would be great if this could store its data in reserved slots instead.

There's no reason for these to be private when they all have operator=
implemented in terms of set() anyway.

This is useful later on so we can update a function's flags with a single
expression rather than reading, updating and setting the flags separately.

In preparation for storing this in a slot, this stores the two values together
in the same field.

In preparation for storing them in a slot, store them in a Value. The value is
encoded as a private uint32 value.

The native function is stored as a private value. This requires casting it to
void* which AFAIU only conditionally supported in the C++ spec but in practice
supported everwhere. We used to do this in other places, although we have
removed them now.

In preparation for storing this in a slot, store it as a JS::Value.
All values including JSScript pointers are stored as private values becuase the
JIT assumes it can access SelfHostedLazyScript pointers and JSScript pointers
in the same way. This means we will still need a trace hook when we store this
data in slots.

We will need to change this later as extended functions will have a different
class, so factor out the check.

GetClonedSelfHostedFunctionNameOffMainThread doesn't seem to be used any more,

Move class fields to fixed slots. I was originally going to remove the function
alloc kinds but they are used to iterate all functions for relazification.
Another complication is that the JIT assumes that the prototype property for
function constructors is always stored in the first dynamic slot, which
requires extended functions have a special size class with six fixed slots.

Whoops only 32-bit, of course. That's probably acceptable.

Functions can now have one of two classes so it's best if JSFunction::class_
doesn't exist or people may use that without thinking.

I ran the awsy tests and the results don't show any conclusive regressions although Base Content JS for 32 bit Windows shows a 3.88% regression at low confidence.

Changing functions to use fixed slots creates a problem when the profiler
tries to get the script for on-stack functions. Unfortunately this can happen
during minor GC after the functions have been moved but before the profiler
data pointing to them has been updated.
The function data itself is mostly intact, but the object header (used for the
shape) is not valid. As far as I can see this only affects the debug assertions
around checking that slot numbers are valid. However the simplest fix is to
suppress the profiler during the intial part of minor GC, until the roots have
been traced (which will update the profiler data).
The patch moves the code to trace the roots in a minor GC to a separate method
and adds a guard to suppress the profiler.œ
What do you think? Alternatively we would have to add a load of 'unchecked'
methods to a buch of accessors on JSFunction, and to NativeObject to get fixed
slots without touching the shape.
