Backport #38679 into release-1.5

The fields are not accessible, so it is awkward to report they exist.

Fixes #37630
Caused issues starting with #34804

)

An undef field should always be treated equal to another undef field of the same type
since there's no other way for the user to tell the difference between these.
These could previously cause inconsistent comparison results or crashes.

* Mark these types as `haspadding` so that they'll not hit the `memcmp` fast path.
* Make sure `jl_egal` and `jl_object_id_` doesn't read bits fields in undef inline immutable field
* Use `emit_getfield_knownidx` in `emit_bits_compare` so that the check can be done more easily

    Handle union fields of the same type in `emit_f_isa` to avoid regression.

* Allow input to `emit_f_isa` to be NULL and lazily emit NULL check if necessary

While this takes a non-trivial amount of space in the system image
(about the same as putting the Method object here, but less than putting
the full edge to the MethodInstance), it is necessary to avoid the
regression #36462 caused by 2e37784.
